Query: 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.
