Anomalous magnetic moment of muon in 3-3-1 models

Abstract

A contribution from new gauge bosons in the $SU(3{)}_C\otimes SU(3{)}_L\otimes U(1{)}_N$ (3 - 3 - 1) models to the anomalous magnetic moments of the muon is calculated and numerically estimated. In the minimal 3 - 3 - 1 model, a lower bound on the bilepton mass at a value of 167 GeV is derived. For an expected precision($\sim 4\times 10^{-10}$) of the BNL measurements the possible lower bounds on masses of the bileptons in the minimal version and in the version with right-handed neutrinos are around 940 GeV and 250 GeV, respectively.
