✦ Synopsis

Theoretical calculations for the W -pair production process at LEP2 in terms of Monte Carlo event generators RacoonWW and KorlaW&YFSWW3 are reviewed. The discussion concentrates on precision predictions for the main LEP2 W W observables. The theoretical precision of the above programs is estimated to be ∼ 0.5% for the total W W cross section σWW , ∼ 5 MeV for the W -boson mass MW , and ∼ 0.005 for the triple-gauge-boson coupling λ = λγ = λZ, which is sufficient for the final LEP2 data analyses.
