摘要:	There exist about 3.7 sigma positive and 2.4 sigma negative deviations in the muon and electron anomalous magnetic moments (g - 2). Also, some ratios for lepton universality in tau decays have almost 2 sigma deviations from the Standard Model. In this paper, we propose a lepton-specific inert two-Higgs-doublet model. After imposing all the relevant theoretical and experimental constraints, we show that these lepton anomalies can be explained simultaneously in many parameter spaces with m(H) > 200 GeV and m(A) (m(H +/-)) > 500 GeV for appropriate Yukawa couplings between leptons and inert Higgs. The key point is that these Yukawa couplings for mu and tau/e have opposite sign.
