Precision predictions for W-pair production at LEP2

الأصل · EN

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 WW observables. The theoretical precision of the above programs is estimated to be 0.5% for the total WW cross section sigmaWW, 5MeV for the W-boson mass MW, and 0.005 for the triple-gauge-boson coupling lambda = lambdagamma = lambdaZ, which is sufficient for the final LEP2 data analyses.
