Essential parts of the first version of Gfitter/GSM have been made available here on 24 February 2013, in http://zfitter.com/gfittergsmMarch2011.tar. Basically, the cxx files, the LICENCE and a readme are contained in the selection.
The contents of the directory gfittergsmMarch2011 seems to date back to 2008. It is sufficient for an investigation of the amount of 'integrations' made from ZFITTER into Gfitter/GSM, observed by the ZFITTER team.
The Gfitter/GSM version, which was actually used for a diploma thesis, several articles, many talks and two webpages, is declared as "not foreseen to become public". This contradicts the licence file, but has relevance for those who respect "conditions of use".
11 September 2011, Gfitter author:
"Dieser Code wurde nicht fuer die Oeffentlichkeit gemacht, und das haben Sie zu respektieren."
[google translator, improved: "This code has not been done for the public, and you have to respect this."]
The cxx files of the March 2011 version differ from those in gfittergsmMarch2011 by few lines of code only.
Essential parts of [typo corr. 27.2.2013:] Gfitter/GSM, as it was made public at the Gfitter webpage in July 2011 [end of typo], have been made available here on 26 February 2013, in http://zfitter.com/gfitter_gsm_21jul2011.tar.
The readme and some documents quoted therein explain why ZFITTER demands a replacement of the Erratum to EPJC60(2009)543 and a retraction of arXiv:1107.0975v1, and why the package Gfitter_21jul2011 and its derivatives are considered by ZFITTER to be illegal.
The re-written Gfitter/GSM package expresses in more than 90 instances that Gfitter/GSM contains 'integrations' from ZFITTER (one line or several lines of code) - according to statements by its authors from Gfitter: M. Goebel, J. Haller, A. Hoecker, K. Moenig.
Taking the findings of the ZFITTER authors A. Akhundov, S. Riemann and T. Riemann on non-authorized hidden copy-paste-adapt actions by Gfitter (on texts and software), plus these statements (on software) ... plus the lack of any quotation of the "integrations" ...
... What else do we need as a proof of scientific misconduct by Gfitter?
When we write "scientific misconduct", we are referring to the DESY GO/BO 2010, the company regulations (BO), Annexes of BO, Annex 5: "Rules for ensuring good scientific practice at DESY and procedures in case of scientific misconduct"
BO page 118, Rule 1:
"Scientific misconduct:
...
Deviations from the good scientific practices ... must be considered as a scientific misconduct.
The following is particularly considered as a scientific misconduct:
...
* Misrepresentations in advertising, applications for support, publications etc.;
* Violation of intellectual property by means of
- unauthorised use under presumption of authorship (plagiarism) as well as presumption or unfounded acceptance of scientific authorship or co-authorship
...

- With a historical overview and a short description of the new program version ZFITTER v.6.44beta -
The text was accepted for publication as PoS(LL2012)036 in the proceedings of the conference "Loops and Legs 2012".
The employer of two of the authors demanded changes which were not possible after "closing" of the conference on 31 January 2013.
After negotiations of the chair of the guest editors T. Riemann with the Editorial Board of PoS, a retraction by PoS on 22 February 2013 was the only solution of the puzzle.
Here is the retracted text: LL2012-retracted-by-PoS-Riemann.pdf

"ZFITTER 1985-2013"
Dedicated to Pena Christova on the occasion of her 70th birthday, arXiv:1302.1395 (Wed, 6 Feb 2013)
Version2: Wed, 6 Mar 2013, with some improvements in the text, added references, and a changed affiliation.
"ZFITTER 1985-2013" contains a historical overview and introduces the new program version ZFITTER v.6.44beta (unpublished).
Just decided:
On 9 February 2013, on behalf of the DESY Board of Directors, the following oral announcements were brought to the knowledge of the ZFITTER spokesperson:
-
The implementation of the
arbitration decision
of the Ombudsman for Science in Germany (dated 3 July 2012), Professor Löwer, has
failed at DESY.
-
The suggestion of the Ombudsman for Science in Germany (22 January 2013) to make the award publicly available will not
be realized by DESY.
-
DESY will perform an internal evaluation (or: investigation?) with the aim of solving the conflict around
ZFITTER and Gfitter.
- The ZFITTER spokesperson is entitled to make the ZFITTER collaboration familiar with the award of the Ombudsman for Science in Germany.
- Concerning item 1 of the DESY Board of Directors' announcement:
Just to remind us of the nature of the conflict:
In March/April 2011, the ZFITTER authors A. Akhundov, S. Riemann, T. Riemann proved that the Standard Model library of the C++ package Gfitter, Gfitter/GSM, contains about 175 formulas taken out of the Fortran package ZFITTER v.6.42 (by emacs).
ZFITTER v.6.42 is available from the CPC software archive at http://cpc.cs.qub.ac.uk/summaries/ADMJ_v2_0.html.
Legal notice:
The CPC software licence may be consulted here: http://cpc.cs.qub.ac.uk/licence/licence.html.
The conditions of use include the need of proper academic citation when the software ZFITTER is used. This includes a reference to the following articles, for the use of the software :
D. Bardin et al., Comp. Phys. Commun. 133 (2001) 229-395
and
A. Arbuzov et al., Comput. Phys. Commun. 174 (2006) 728-758
The parts of Gfitter/GSM with relevance to the ZFITTER-Gfitter negotiations are available here: http://zfitter.com/gfittergsmMarch2011.tar.
Legal notice:
The Gfitter package was downloaded by legal operations on 2 March 2011 from the webaddress http://atlas-sw.cern.ch/cgi-bin/viewcvs-atlas.cgi/groups/catsusy/Gfitter/gsm/. It is closed now. A copy of the webpage may be seen here: atlas_Index_of_groups_catsusy_Gfitter_gsm.htm.
The licence of Gfitter in March 2011 is reproduced here: gfitter-license-27-02-2011-search. htm.
We have to add that, according to the CPC licence statement of ZFITTER, the following two articles have to be quoted for the use of ZFITTER v.6.42 in the Gfitter project:
D. Bardin et al., Comp. Phys. Commun. 133 (2001) 229-395 and A. Arbuzov et al., Comput. Phys. Commun. 174 (2006) 728-758.
In this respect, the Gfitter licence of March 2011 is not correct. It is part of the systematic conceal of using ZFITTER by Gfitter.
The article EPJC60(2009)543v3 (with a deliberately wrong Erratum EPJC71(2011)1718 (corresponding to hep-ph/0811.0009v4) and a diploma thesis (Univ. Hamburg) describe the and rely on the software, and contain additionally about 5 pages of text tracing back to texts of ZFITTER authors (also 'integrated' by emacs).
The take-overs are performed by non-authorized hidden copy-paste-adapt. For details see below.
About 33 Gfitter publications of different importance, published between December 2009 and Spring 2011, support the impression that Gfitter relies only on the work of its authors, without a proper reference to the use of the above-mentioned ZFITTER resources. For details see below.
The responsible authors are Martin Goebel, Professor Dr. Johannes Haller (Univ. Hamburg, Univ. Goettingen, Univ. Hamburg), Dr. Andreas Hoecker (CERN), Dr. Klaus Moenig (DESY).
The conflict ...
... is described in the one-page-memo "Memorandum on ZFITTER/Gfitter" by Prof. A. A. Akhundov, Prof. P. Christova, Dr. S. Riemann, Dr. T. Riemann et al., dated 4 November 2012. There are two auxiliary documents available (see above): T. Riemann, "Backup information for `Memorandum on ZFITTER/Gfitter v.2'" and A. Akhundov, "Letter to Ombudsman for Science in Germany, Prof. W. Loewer, Bonn and to Chairman of the Board of Directors of DESY, Prof. H. Dosch, Hamburg".
ZFITTER expects that the situation gets
- acknowledged
- estimated
- cleaned.
According to
- the internationally accepted ethical rules of academic scientific work
- the recommendations of Deutsche Forschungsgemeinschaft by Bjorn Wiik, DESY et al. of 1998, see DFG - Recommendations of the Commission on Professional Self Regulation in Science - Proposals for Safeguarding Good Scientific Practice, January, 1998">
- the "Procedure and company regulations (GO/BO) for Deutsche Elektronen-Synchrotron DESY", Attachments of the BO, No. 5 "Rules for ensuring good scientific practice at DESY and procedures in case of scientific misconduct", see Attachment 5
- the regulations by Springer Verlag, Policy_on_Publishing_Integrity2010
The one-page-memorandum by ZFITTER (see below), dated 4 Nov 2012, is actual (per 27 February 2013).
- Concerning item 2 of the DESY Board of Directors' announcement:
The award of the Ombudsman for Science in Germany (dated 3 July 2012), Professor Löwer, may be found here in English translation: arbitration decision.
The translation is licenced under the creative commons licence.
-
Concerning item 3 of the DESY Board of Directors' announcement:
There have been so far four moderations of the ZFITTER-Gfitter conflict at DESY, plus one investigation by the Editors-in-Chief of "European Physical Journal C" of Springer Verlag. They all ended without a solution of the conflict, part of them with conclusions:
- The "Buchmüller report"
The ombudspersons at DESY performed an investigation of the ZFITTER/Gfitter conflict from 3 March 2011 till 18 April 2011.
Committee leader Professor W. Buchmüller submitted to the DESY Board of Directors the final report on 18 April 2011 with the results of so-called 'preliminary' investigations and with recommendations.
The report is confidential.
A central statement became later quoted in the Löwer report: "A diploma thesis derives from ZFITTER in the sense that 8200 lines have been taken over by copying from ZFITTER." Seemingly, the 'integrations' of text passages in a diploma thesis and an article were not reported.
From the Decision of the DESY Board of Directors (21 April 2011) one may conclude that no serious scientific misconduct has been reported.
- The "Naumann report"
Nevertheless, a moderation session with representatives from ZFITTER and Gfitter has been organized on behalf of Professor H. Dosch, spokesperson of the DESY Board of Directors, on 11 May 2011 in Zeuthen.
In the course, negotiations were undertaken to find an agreement between ZFITTER and Gfitter. These failed at the end of July 2011 in a desastrous disorder. Moderator Professor T. Naumann submitted to Professor H. Dosch and to ZFITER and Gfitter the final report on 24 Sep 2011. The report is signed by Professor T. Naumann and Dr. G. Weiglein (co-moderator, nominated by Gfitter) and approved by Gfitter. The report is not signed by Professor S. Moch (co-moderator, nominated by ZFITTER) and not approved by ZFITTER. The report and the reply by ZFITTER are not confidential.
An Erratum to EPJC60(2009)543 was submitted by Gfitter to EPJC on 20 July 2011 as part of the planned negotiations. Because the final negotiations failed few days later, the Erratum turned out to be senseless and wrong. The Erratum is, naturally, authored exclusively by Gfitter, and so only Gfitter carries responsibility for the submission, and for the need of a replacement.
See for more details in gfitter_gsm_21jul2011.tar.
- The "Dosch initiative"
The ZFITTER spokesperson proposed on 12 August 2011 to sign a "ZFITTER-Gfitter agreement".
See here: 2011-08-12-draft-agreement
Professor H. Dosch initiated direct negotiations of ZFITTER and Gfitter with the aim to find an agreement, from 31 August 2011 till 13 October 2011.
An intermediate version of the draft agreement is 2011-09-15-draft-agreement
Finally, the initiative failed.
If there is any final report, it is not known to ZFITTER.
- Springer Publisher: The "Caron reply" and the "Bethke report"
Since 8 April 2011, ZFITTER tried to find contact with Editors-in-Chief of EPJC Professor S. Bethke and Dr. G. Weiglein concerning the Gfitter problem.
On 5 September 2011, the editorial office recommended to contact in case these two Editors-in-Chief, email01-von-epjc-editorialoffice.pdf.
On 12 September 2011, the editorial office explained in short the approach to cases of suspected misconduct, email02-von-epjc-editorialoffice.pdf.
Since 20 September 2011, there was an exchange of opinions with Professor S. Bethke, in accordance with the official rules of Springer Verlag.
On 23 September 2011, a first complaint about the so-called 'main paper' of Gfitter, EPJC60(2009)543, was sent to the Editor-in-Chief of EPJC, Professor S. Bethke. It consisted of a formal letter and attached documents (about 1 MB).
Available on request.
The complaint was rejected on formal grounds by the publisher, Dr. Caron. Evidently, it would be difficult to fulfill the conditions formulated by the publisher, see: Email Dr.Caron to Dr. Riemann.
On 24 October 2011, another complaint was sent to professor Bethke with additional information.
Available on request.
On 3 November 2011, an intermediate trial was undertaken to fulfil part of the formal conditions formulated by the publisher.
Available on request.
In doing so, it became evident that there was absolutely no chance to fulfil the formal conditions formulated by the publisher.
On 23 December 2011, a second, completely modified complaint of 37 pages was sent to Professor S. Bethke for EPJC; see letter-to-springer-editor-2011-12-23. Accompanied by a huge attachment.
On 26 January 2012, the complaint was rejected and no appeal was allowed. With a reasoning. See Letter_Riemann.pdf. The argument of the 3-pages document is basically that Gfitter quoted correctly.
One comment only: In EPJC60(2009)543, ZFITTER is mentioned (and quoted) twice: for numerical cross-checks and for a 'procedure'. But, the ZFITTER software or its 'integrations' or the text integrations from ZFITTER authors' texts are not mentioned at all.
The Bethke report contradicts not only in general to the citation rules of academic research, but also to the rules of Springer Verlag for the treatment of scientific misconduct, Policy_on_Publishing_Integrity2010.
[Added March 2013:]
On 12 February 2012 we indicated to Springer publisher and to Gfitter that, independent of Springer's decision on EPJC60(2009)543, there is a new Erratum to that article, which contains incorrect information, letter-to-Springer-Gfitter.pdf
On 15 February 2012, the decision by the Editors-in-Chief was questioned against the legal department of Springer Verlag, letter-to-rechtsabteilung.pdf.
On 21 February 2012 the decision got finally confirmed , letter-from-rechtsabteilung.pdf.
On 14 September 2012, because the last complaint remained unanswered, we wrote a letter to all the 60 editors of EPJC, which also remained unanswered so far, email-to-all-epjc-editors.pdf.
4 November 2012: The status is not satisfactory for ZFITTER, and so Springer publisher is mentioned in the one-page-memo of ZFITTER (with accompanying documents).
[Added March 2013:] We refer here also to the recent findings of a German court on proper citations, in German language:
VG Freiburg Urteil vom 23.5.2012, 1 K 58/12
Rücknahme der Verleihung des Doktorgrades - hier: Plagiatsvorwürfe

- Deutsche Forschungsgemeinschaft DFG: The "Löwer report"
On 14 November 2011 the DESY Board of Directors asked the Ombudsman for Science in Germany, Professor Löwer, to perform an investigation.
30 November 2011 - The ZFITTER spokesperson asked also for an investigation.
Since 2 February 2012 there is the file number "A-42/2011 - ZFITTER/Gfitter/DESY".
26 June 2012 - A series of meetings of professor Löwer with T. Riemann (ZFITTER spokesperson), with professor J. Haller and K. Moenig (for Gfitter), with T. Riemann and K. Moenig happened at DESY.
On 3 July 2012 the arbitration award was submitted by Professor Löwer.
An English translation is Schiedsspruch_prof_loewer-EN-06Jul2012.pdf.
Since July 2012, no visible actions were undertaken to fulfill the award.
On 9 February 2013 DESY announced to ZFITTER that the fulfilment of the Löwer award failed.
We are now awaiting the final statement of Professor Löwer.
There happened an interesting action:
-
The "Retraction of Gfitter's article arXiv:1107.0975v1" ...
... by Springer Verlag.
The article arXiv:1107.0975v1, "Updated Status of the Global Electroweak Fit and Constraints on New Physics" by Gfitter, M. Baak (CERN) et al., was
- submitted to EPJC on 5 July 2011
- accepted for publication by EPJC on 12 September 2011
but was never printed.
While, we see in the printed article "Updated Status of the Global Electroweak Fit and Constraints on New Physics" by Gfitter, M. Baak (CERN) et al., as EPJC72(2012)2003:
- Received: 2 January 2012
- Revised: 19 April 2012
- Published online: 17 May 2012
The corresponding preprint is arXiv:1107.0975 [v2] Tue, 11 Sep 2012 14:18:50 GMT (888kb).
At first glance and formally the same paper, in fact another article as seen from EPJC.
The only possible conclusion:
EPJC retracted the article "Updated Status ..." after acceptance on 12.9.2011 and printed instead the article "Updated Status ..." which was submitted on 2.1.2012 and published online on 17 May 2012. The authors lists of the two articles arXiv:1107.0975v1 and arXiv:1107.0975v2 = EPJC72(2012)2003 differ. This also proves that they are different articles.
There happened also several non-investigations and non-events around the ZFITTER-Gfitter negotiations. We like to mention few of them:
- The ombudsman of CERN ...
... refused to deal with the negotiations due to lack of time and lack of mandate (21 May 2012). In fact, from who-can-use-ombuds-services we learn that this is correct: "All members of personnel have access to the services of the Ombuds. In addition, any other person working at, or on behalf of, CERN also has access to the Ombuds." And others have no access.
-
The MIN faculty of Hamburg University ...
dealt with the ZFITTER-Gfitter negotiations, confidentially, and did not observe irregularities (information by Dr. K. Moenig, 26 June 2012). The faculty refuses from any contact with ZFITTER.
-
Meeting "Zeuthen II" ...
... was agreed upon as an informal, private meeting of J. Bluemlein, K. Moenig, T. Naumann, T. Riemann at Zeuthen on 20 November 2012, a kind of follow-up of "Zeuthen I" on 11 May 2011 (see above, the "Naumann report").
The Gfitter representative finally did not come.
Besides the one-page-memo of ZFITTER of 4 November 2012, a preparatory text with facts and views from the ZFITTER side was prepared for "Zeuthen II", 2012-11-20-intro-Zeuthen-II.pdf. It was not exchanged with Gfitter, because the corresponding document from Gfitter was not presented to the organizers.
- The "Buchmüller report"
-
Concerning item 2 of the DESY Board of Directors' announcement:
The arbitration decision by Professor Löwer has been translated into English and is publicly available from this webpage.
-
Concerning item 3 of the DESY Board of Directors' announcement:
The announced fifth investigation at DESY, the sixth one when the EPJC study is added, certainly will solve the conflict.
-
Concerning item 4 of the DESY Board of Directors' announcement:
Statement by Professor Löwer, 23 July 2012, to the ZFITTER spokesperson:
"You should inform ZFITTER on the arbitration award."
This has been done that time.
ZFITTER news as of January 2013:
Letter_Riemann.pdf, letter from the Editors-in-Chief of "European Physics Journal C", dated 26 January 2012, to the ZFITTER spokesperson.
Concern: The article EPJC60(2009)543 is carefully justified as a correct publication according to the "common sense approach" to plagiarism. Appeal is not allowed. Confirmation by the Legal Department of Springer Publisher few days later.
[added Sep 2012]
ZFITTER news as of December 2012:
Talk by T. Riemann at "6th Annual Workshop of the Helmholtz Alliance 'Physics at the Terascale'", chaired by T. Behnke and C. Zeitnitz, 03 to 05 December 2012 at Hamburg, Germany, in Parallel Session II "Electroweak and QCD Physics", Conveners: K. Rabbertz, S. Pozzorini, S. Schumann, G. Heinrich, K. Lohwasser, on "ZFITTER and LHC physics". The slides at the conference webpage have been 'improved' afterwards by exchanging page 23. The original page 23 may be found here: slide 23.
ZFITTER news as of November 2012:
Because
- there is no visible progress in the realization process of the arbitration award on Gfitter of the Ombudsman for Science in Germany, dated as of 3 July 2012,
- and there is little overlap between the expectations of the ZFITTER collaboration with the award,
- and there is a grain of imbalance in the sanctions decided so far,
we summarized the ZFITTER expectations in a one-page-memo, dated 4 November 2012:
Memorandum on ZFITTER/Gfitter
[back to 15 December 2013]
authored by Professor A. A. Akhundov, Professor P. Christova, Dr. S. Riemann, Dr. T. Riemann et al.
The two auxiliary documents "Backup information for `Memorandum on ZFITTER/Gfitter'" by T. Riemann and "Letter to the Ombudsman for Science in Germany and to the Chairman of the Board of Directors" by A. Akhundov can be made available on request.
Among those who were asked to recognize the points of view of the ZFITTER collaboration are:
- Gfitter collaboration
- Ombudsman for science in Germany
- Chairperson and members of the Directorate
- Chairperson of the administrative council
- President of the Helmholtz-Gemeinschaft
- Scientific Coordinators and Scientific Manager of the "Helmholtz Alliance `Physics at the Terascale'" [8 Dec 2012]
[15,16,19 Nov 2012]
ZFITTER news as of October 2012:
An institution took a disciplinary measure according to German labor law in the arbitration procedure Gfitter ZFITTER against the ZFITTER spokesperson on 10 October 2012 based on a decision by its Board of Directors.
Original phrasing in German: "... Beschluss zum Schiedsgerichtsverfahren Gfitter ZFITTER - Arbeitsrechtliche Massnahmen Tord Riemann".
This is the first and so far only sanction in the ZFITTER-Gfitter negotiations. [15 Nov 2012]
[Added March 2013: On 20 March 2013, another disciplinary measure was taken against the ZFITTER spokesperson. See above.]
ZFITTER news as of September 2012:
Open Letter to the Editorial Board of "European Physics Journal C", 14 September 2012
Concern: Again: The Erratum to EPJC60(2009)543 should be retracted because it contains wrong statement on ZFITTER/Gfitter software and does not comment the "integrations" of texts authored by ZFITTER persons into EPJC60(2009)543. Further, EPJC60(2009) and EPJC71(2011)1718 are compared.

"ZFITTER - 20 years after"
Tord Riemann, DESY, Zeuthen, Germany
Talk on the ZFITTER history, held at LL2012, Int. Workshop "Loops and Legs in Quantum Field Theory", 15-20 April 2012, Wernigerode, Germany
ZFITTER
is a Fortran package for the evaluation of radiative corrections (quantum corrections), as predicted in the Standard Model of elementary particles, to a variety of observable quantities, notably those related to the Z-boson resonance peak studied at LEP, CERN.
It is supported since about 1985.
Authors of ZFITTER:
A. Akhundov, A. Arbuzov, M. Awramik, D. Bardin, M. Bilenky, A. Chizhov, P. Christova, M. Czakon, O. Fedorenko, A. Freitas, M. Grünewald, M. Jack, L. Kalinovskaya, A. Olshevsky, S. Riemann, T. Riemann, M. Sachwitz, A. Sazonov, Yu. Sedykh, I. Sheer, L. Vertogradov, H. Vogt.
ZFITTER
has been used for many experimental and phenomenological studies.
The actual version is ZFITTER v. 6.43 (released 17 June 2008).
ZFITTER authors claim to hold personal copyrights and licence rights.
ZFITTER v.6.44 has been prepared for release.
After clarification of copyright and licence problems, a release might become possible.
The creation of ZFITTER would have been impossible without the generous help of the community and the long-term co-operation with G. Passarino and the TOPAZ0 team (G.P. and G. Montagna, O. Nicrosini, F. Piccinini, R. Pittau), because the complexity of the standard model's fortranization deserves more than one independent implementation.
For those who want to know more about the complexity of the theoretical framework, we recommend the book "The Standard Model in the Making: Precision Study of the Electroweak Interactions", Oxford University Press, USA (December 9, 1999) by D. Bardin and G. Passarino.
Other helpful documents are e.g. "Electroweak Working Group Report", a part of: D. Bardin, W. Hollik, G. Passarino (eds.), "Reports of the working group on precision calculations for the Z resonance", CERN 95-03 (31 March 1995), and "Precision Calculation Project Report" by D. Bardin, M. Grunewald, G. Passarino.
PDG
The PDG -Particle Data Group with its regularly updated survey The Review of Particle Physics uses since many years for the determination of the Z boson properties and the analysis of the Standard Model, among other material, ZFITTER. For examles, see rpp2011-rev-z-boson, rpp2011-rev-standard-model, rpp2011-list-z-boson. .
LEPEWWG - the LEP electroweak working group
The perhaps most important applications for the elementary particle physics community may be found at the webpage of the LEP electroweak working group LEPEWWG. The prediction of the Higgs mass, assuming the Standard Model being valid, derived from radiative corrections to precision observables measured at LEP and other facilities, is visualized in the popular Blue Band Plot of the LEPEWWG.
s10_blueband.epss10_blueband.pdf
The plot is made with the ZFITTER package v. 6.43 [2008].
Updates may be found here too, e.g. under the subject "LEP/TEV EW WG Plots for Summer 2011"; version 6.43 of ZFITTER is furtheron used.
The Cracow/Knoxville Monte Carlo Generator Family
An important class of applications are precision Monte Carlo programs: Some of them link parts of ZFITTER.
E.g. the "Precision Monte-Carlo Event Generator KK For Two-Fermion Final States In e+e- Collisions" by S. Jadach, B. Ward, Z. Was, see hep-ph/9912214", Comput.Phys.Commun. 130 (2000) 260-325.
This collaboration uses the ZFITTER library dizet v.6 for the calculation of higher order corrections in the electroweak/QCD Standard Model
SMATASY, ZEFIT, BHAGENE etc.
There are a variety of projects with use of the ZFITTER package by so-called interfaces [written by the users] and, of course, with a correct reference to ZFITTER, usually with indication of the exact number of the ZFITTER version used.
We like to mention:
SMATASY - a project of M. Grunewald, S. Kirsch, T. Riemann, J. Rose for the description of the Z boson line shape in a model-independent approach (inspired by S-matrix theory)
ZEFIT - a project of A. Leike and S. Riemann for a model-independent approach to some classes of theories beyond the Standard Model with extra gauge degrees of freedom and thus with additional, heavy neutral gauge bosons
BHAGENE - a Monte-Carlo program of J. Field and T. Riemann for Bhabha scattering at LEP
H. Stenzel's modifications to ZFITTER v.6.42 - unpublished interface for ZFITTER v.6.42 with a proper implementation of the QCD renormalization scale. A study of variation of the mu-scale indicates a perturbative uncertainty of about 1 % for hadronic observables at the Z pole.

Why the headline "Wo ZFITTER drin ist, soll auch ZFITTER draufstehen"?
[In English by google translator: "Where there is ZFITTER should also stand upon ZFITTER".]
Or simpler: "What contains ZFITTER should also cite ZFITTER"
Many of the ZFITTER authors never applied the package by themselves for e.g. a physical analysis -- despite the fact that its creation, description and support deserve a lot of time and of intellectual effort.
Since about 1985, and with continous support by JINR Dubna, Russia, we care about ZFITTER for the benefit of the scientific community and in order to support scientific progress.
Besides many other publications, descriptions of the software have been published several times, notebly a total of about 350 pages in the following articles:

As a payback for the activities around ZFITTER, we expect from the scientific community that users of ZFITTER give fair reference to the software package and its roots.
This was clearly expressed since many years on this homepage:
See here.
In addition, there are two CPC license agreements, see at http://cpc.cs.qub.ac.uk/summaries/ADMJ, for the articles describing ZFITTER, Comp. Phys. Commun. 133 (2001) 229-395 and Comput. Phys. Commun. 174 (2006) 728-758.
Gfitter
Since 2007, the well-known C++ package Gfitter is another application of the ZFITTER software package.
Unfortunately, this had not been expressed by Gfitter's webpages or by the Gfitter software [which is handled as being proprietary although the formal licence is of the open-source type] or by the more than 35 publications between Dec 4, 2007 and July 4, 2011.
In arXiv:1107.0975 (July 5, 2011), the authors of Gfitter express:
"The calculations of the partial and total widths of the Z and of the total width of the W boson have been integrated from the ZFITTER package."
Unfortunately, they refer for that to a software package which does not exist and will never exist. So the statement remained unclear concerning its content. The preprint arXiv:1107.0975 was accepted for publication in EPJC, a Springer scientific journal, in Septemer 2011, but never was published.
Gfitter authors in July 2011: Max Baak (CERN, Switzerland), Henning Flächer (CERN, Switzerland), Martin Goebel (U. Hamburg and DESY, Germany), Johannes Haller (U. Göttingen, Germany), Andreas Höcker (CERN, Switzerland), Dörthe Ludwig (U. Hamburg and DESY, Germany), Klaus Mönig (DESY, Germany), Matthias Schott (CERN, Switzerland), Jörg Stelzer (DESY, Germany).
The non-authorized hidden copy-paste-adapt (they call it `integration') of ZFITTER software into Gfitter has been performed in 2006 under responsibility of the authors group of Gfitter/GSM: Martin Goebel [diploma student at Univ. Hamburg, Germany], Johannes Haller [professor at Univ. Hamburg, Germany], Andreas Höcker (CERN staff) and Klaus Mönig (leading scientist at DESY, Zeuthen) and consists of a rewriting of ZFITTER Fortran code into Gfitter c++ code. Code by G. Degrassi et al. and by B. Kniehl, which was attached to the ZFITTER package (and quoted there correctly), has also been `integrated'.
The legal status of these non-authorized hidden code `integrations' is not agreed upon between the ZFITTER and Gfitter groups [status 31 October 2011; unchanged 08 June 2012; unchanged June 2012; unchanged January 2013]. ZFITTER considers the Gfitter/GSM subpackage software as not legally created.
There are also non-authorized hidden copy-paste-adaptations of about five pages of ZFITTER text into publications of Gfitter people (article EPJC60(2009)543 and a diploma thesis).
The above statements may be checked by visiting the following documents:
