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

摘要

A contribution from new gauge bosons in the SU(3)(C) circle times SU(3)(L) circle times 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 (similar to 4 x 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.
