摘要：

A measurement of the reaction e+e- was performed using a beam-stop source of e. Based upon 23435 events, we obtain a cross section of ee)=[9.91.5(stat)1. 0(syst)]×10-42 cm2 ×[E (GeV)]. This reaction is mediated by the exchange of W and Z bosons and is thus sensitive to the interference between them. This interference is measured to be -1.070.17(stat)0.11(syst), consistent with the destructive interference (-1.08) predicted by the standard model. © 1990 The American Physical Society.
