The participation in a software project may be due to a variety of activities, including creation of code, debugging, creation of description, ruling the team etc.
For legal reasons we mention here that some of us were in a shorter term than indicated active with the software itself but rather worked - within the project - on description etc.
We indicate the period of activity if it is not continously.
It is not easy to reasonably date the begin of the project.
ZFITTER is intended to describe electroweak and QCD effects in physics related to e+e- annihilation
plus related topics.
The very first studies of the Dubna group in the Standard Model are due to D. Bardin and O. Fedorenko:
"On High Order Effects For Fermion Elastic Scattering Processes In Weinberg-salam Theory. 1. Renormalization Scheme",
D.Yu. Bardin (Dubna, JINR), O.M. Fedorenko (Moscow State U.). JINR-P2-11413. Mar 1978. 24 pp.
"On High Order Effects For Fermion Elastic Scattering Processes In Weinberg-salam Theory. 2. Calculation Of One Loop Diagrams",
D.Yu Bardin (Dubna, JINR), O.M. Fedorenko (Moscow State U.). JINR-P2-11414. Mar 1978. 30 pp.
Our first paper on QED corrections in e+e- annihilation was:
"Some Integrals For Exact Calculation Of Qed Bremsstrahlung",
A.A. Akhundov (Baku, Inst. Phys.), D.Yu. Bardin (Dubna, JINR), O.M. Fedorenko (Petrozavodsk State U.), T. Riemann (Dubna, JINR). JINR-E2-84-777. Dec 1984. 10 pp.
A bit arbitrarily, one may choose as one of the first papers in the ZFITTER project: A. Akhundov, D.
Bardin, T. Riemann on "Hunting the hidden standard Higgs", Phys.Lett. B166 (1986) 111, submitted in
1985. What was programmed for this article, became later ZFITTER.
