Reaction E exp + E exp - Implies mu exp + mu exp - (Or tau exp + tau exp - ) with Two Neutral Weak Bosons at LEP Energies

摘要

The standard Salam-Weinberg model of weak and electromagnetic interactions is in agreement with almost all the experimental data. Recently the discovery of parity violation in reactions of polarized electrons on nucleons at SLAC has provided a remarkable confirmation of the standard model. The model-independent formulae giving the cross-section, the charge asymmetry and the longitudinal polarization of the final leptons are given for e exp + e exp - implies mu exp + mu exp - . The general features of models based on the symmetry groups are summarized. The predictions of two of them are presented for the reactions e exp + e exp - implies mu exp + mu exp - .
