AbstractThe muon anomalous magnetic moment is investigated in the standard model with two Higgs doublets (S2HDM) motivated from spontaneous CP violation. Thus all the effective Yukawa couplings become complex. As a consequence of the nonzero phase in the couplings, the one-loop contribution from the neutral scalar bosons could be positive or negative relying on the CP phases. The interference between one- and two-loop diagrams can be constructive in a large parameter space of CP phases. This will result in a significant contribution to muon anomalous magnetic moment even in the flavor conserving process with a heavy neutral scalar boson (m(h)similar to 200 GeV) once the effective muon Yukawa coupling factor is large (\xi (mu)\ similar to 50). In general, the one-loop contributions from lepton flavor changing scalar interactions become more important. In particular, when all contributions are positive in a reasonable parameter space of CP phases, the recently reported 2.6 sigma experiment versus theory deviation can be easily explained even for a heavy scalar boson with a relatively small Yukawa coupling in the S2HDM.
