Muon Anomalous Magnetic Moment in the Left-Right Symmetric Model

Abstract

The measurement of muon anomalous magnetic moment provides a test of the standard model and of the physics that lies beyond it. Currently, there is a deviation of 2.6σ between the standard model prediction and the experimental results. In this work, the contribution of heavy gauge bosons from the left right symmetric model (LRSM) is calculated. We find that the LRSM can give a relatively small but non-negligible extra weak contribution to the muon anomalous magnetic moment and can reduce the deviation of Δaμ from 2.6σ for the SM to 2.5σ for the LRSM model.
