# Parity Violation Effect in Atomic Physics and the Structure of Neutral Currents in Gauge Theories

## Abstract

We study here three models, namely, the SU(2) \( \otimes \) U(1) model, the SU_{L}(2) \( \otimes \) SU_{R}(2) \( \otimes \) U(1) model and the SU_{L}(2) \( \otimes \) SU_{L}(2) \( \otimes \) U(1) model, which seem to be the most natural extensions of the Weinberg-Salam model in order to accomodate the recent atomic Bismuth experimental results. The differences between the model predictions in neutrino reactions are small except for the elastic υμe and υμe cross sections. We remark on the other specific experiments which could provide meaningful checks between these models. We also comment on the “naturalness” of each model.

What the present experiments have measured is thus the parity violation effect induced by the vector hadronic neutral currents and the axial-vector electron currents.Google Scholar

- 15.8 quarks and 8 leptons were previously proposed in a different context (see T.C. Yang, Phys.Lett. 65B, 358 (1976)). We received a recent preprint by N.A.B. Bég, R.N. Mohapatra, A. Si lin and H.-S. Tsao who have discussed 8 quarks and 24 leptons in a SU
_{L}(4) \( \otimes \) SU_{R}(4) \( \otimes \) U(1) model. Note that under SU(4) symmetry, 8 quarks would require 24 leptons in order to cancel anomalies.CrossRefGoogle Scholar - 16.The main point is that t, b, g, h quarks are heavier than \(\tau \) lepton. The \(\tau \) decay via “flavor” SU(2) interactions is just like the case of a sequential heavy lepton. The only place where the “fragrance” interaction contributes is in \(\tau \,\, \to \,\,e{\nu _e}{\nu _\tau }\). We thus find that \(\frac{{BR\left( {\tau \to {\nu _\tau }e{{\mathop \nu \limits^ - }_e}} \right)}}{{BR\left( {\tau \to {\nu _\tau }\mu \,\,\mathop {{{\mathop \nu \limits^ - }_\mu }}\limits^{} } \right)}}\,\, \ne \,\,1\) Google Scholar
