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

A contribution from new gauge bosons in the SU(3)C⊗SU(3)L⊗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 (∼4×10−10) 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.
