Analysis of some observable effects of weak neutral currents coupled to charged leptons

Abstract

We have analyzed the parity-violating effects in the processes e+e̅ →k₁+k₂+X, k₁+k₂→e+e̅ +X, and e+k₁→e+k₂+X, where e, e̅ are the electron, positron states, k₁ k₂ are the hadron states, and X is the inclusive hadron state, due to the possible coupling of weak neutral currents to charged leptons. We estimate that for gauge theories of the weak interaction, the parity-violating asymmetry parameter for the distribution in e+e̅ →π⁺+π^-+π⁰ may be of the order of 5% in the resonance region of the A₁ meson and experimentally observable.
