The muon anomalous magnetic moment and a new light gauge boson

Abstract

It is shown that the 2.6 $\sigma$ discrepancy between the predicted and recently measured value of the anomalous magnetic moment of positive muons could be explained by the existence of a new light gauge boson X with a mass $M_X\le O(5)GeV$. Phenomenological bounds on the X coupling are discussed.
