Semi-analytic predictions for W pair production at 500 GeV

We give a short review on the semi-analytic approach to off-shell W pair production at 500 GeV and above. Numerical calculations are performed with the Fortran program GENTLE v. 2.0 and its upgrade. Recent extensions include: (i) angular distribution for the CC11 process with LLA QED corrections; (ii) anomalous couplings. As an application we study the sensitivity of total cross-section and forward-backward asymmetry to anomalous couplings. A noticeable sensitivity from the asymmetry appears only for a parity-violating anomalous coupling.

GENTLE/4fan v.2.0 - A Program for the Semi-Analytic Calculation of Predictions for the Process e+e- -> 4f

We describe version 2.0 of the Fortran program GENTLE/4fan for the semi-analytic computation of cross-sections and distributions in four-fermion production in e+e- annihilation. GENTLE/4fan covers all charged current and neutral current our-fermion final states with no identical particles, no electrons, and no electron neutrinos in the final state. Initial state radiation representing the most relevant quantum corrections and anomalous triple gauge boson couplings have been included.
