We describe ZFITTER, a Fortran program based on a semi-analytical approach to fermion pair production in e + e − annihilation at a wide range of centre-of-mass energies, including the PETRA, TRISTAN, LEP1/SLC, and LEP2 energies. A flexible treatment of complete O(α) QED corrections and of some higher order contributions is made possible with three… (More)
In this paper we describe a check of the implementation of SANC system generated modules into the framework of the WINHAC Monte Carlo event generator. At this stage of work we limit ourselves to inclusion of complete one-loop electroweak corrections to the charged-current Drell–Yan process. We perform tuned comparisons of the results derived with the aid of… (More)
The project, aimed at the theoretical support of experiments at modern and future accelerators — TEVATRON, LHC, electron Linear Colliders (TESLA, NLC, CLIC) and muon factories, is presented. Within this project a four-level computer system is being created, which must automatically calculate, at the one-loop precision level the pseudo-and realistic… (More)
One-loop corrections to the Drell-Yan process in SANC (I). The charged current case. Abstract Radiative corrections to the charged current Drell-Yan processes are revisited. Complete one-loop electroweak corrections are calculated within the automatic SANC system. Electroweak scheme dependence and the choice of the factorization scale are discussed.… (More)
Radiative corrections to the neutral current Drell–Yan-like processes are considered. Complete one-loop electroweak corrections are calculated within the SANC system. Theoretical uncertainties are discussed. Numerical results are presented for typical conditions of LHC experiments.
Radiative corrections to neutrino deep inelastic scattering are revisited. One–loop electroweak corrections are re–calculated within the automatic SANC system. Terms with mass singularities are treated including higher order leading logarithmic corrections. Scheme dependence of corrections due to weak interactions is investigated. The results are… (More)
The atomic parity-violation (APV) parameter Q W for a nucleus with n neutrons and z protons has been included in the list of pseudo-observables accessible with the codes TOPAZ0 and ZFITTER. In this way one can add the APV results in the LEP EWWG 'global' electroweak fits, checking the corresponding effect when added to the existing precision measurements.
