W对产生阈附近的四费米子产生

Four-fermion production near the W-pair production threshold

P. Falgari

摘要:

我报告了最近在不稳定粒子有效场论框架下获得的过程e- e+ -> mu- nubar_mu u dbar X的总产生截面的结果,该截面在W对产生阈值附近,达到了γ W/MW α v ^2的次领先阶。剩余的理论不确定性和它们对W质量的实验测定的影响进行了讨论。

英文摘要:

I report on recent results for the total production cross section of the process e- e+ -> mu- nubar_mu u dbar X near the W-pair production threshold up to next-to-leading order in GammaW/MW alpha v^2 obtained in the framework of unstable-particle effective field theory. Remaining theoretical uncertainties and their impact on the experimental determination of the W mass are discussed.
