Anomalous neutrino interaction, muong−2, and atomic parity nonconservation

We propose a simple unified description of two recent precision measurements which suggests new physics beyond the standard model of particle interactions, i.e., the deviation of ${\sin }^2{\theta }_W$ in deep inelastic neutrino-nucleon scattering and that of the anomalous magnetic moment of the muon. Our proposal is also consistent with a third precision measurement, i.e., that of parity nonconservation in atomic cesium, which agrees with the standard model.
