Title: ZFITTER: A Semi-analytical program for fermion pair production in e+ e- annihilation, from version 6.21 to version 6.42

Journal Article ·
OSTI ID:878972

ZFITTER is a Fortran program for the calculation of fermion pair production and radiative corrections at high energy e{sup +}e{sup -} colliders; it is also suitable for other applications where electroweak radiative corrections appear. ZFITTER is based on a semi-analytical approach to the calculation of radiative corrections in the Standard Model. They present a summary of new features of the ZFITTER program version 6.42 compared to version 6.21. The most important additions are: (1) some higher-order QED corrections to fermion pair production, (2) electroweak one-loop corrections to atomic parity violation, (3) electroweak one-loop corrections to {bar {nu}}{sub e}{nu}{sub e} production, (4) electroweak two-loop corrections to the W boson mass and the effective weak mixing angle.
