The muon g – 2 for low-mass pseudoscalar Higgs in the general 2HDM

The two-Higgs doublet model is a simple and attractive extension of the Standard Model. It provides a possibility to explain the large deviation between theory and experiment in the muon g – 2 in an interesting parameter region: light pseudoscalar Higgs A , large Yukawa coupling to τ -leptons, and general, non-type II Yukawa couplings are preferred. This parameter region is explored, experimental limits on the relevant Yukawa couplings are obtained, and the maximum possible contributions to the muon g – 2 are discussed.
