Abstract

Combining the multi-lepton searches at the LHC, we study the possibilities of accommodating the new data of muon and electron g-2 anomalies in the lepton-specific inert two-Higgs-doublet model. We take the heavy CP-even Higgs as the 125 GeV Higgs, and find the muon and electron g-2 anomalies can be explained simultaneously in the region of 5 GeV < m_h<60 GeV, 200 GeV <m_A< 620 GeV, 190 GeV <m_H^±< 620 GeV for appropriate Yukawa couplings between leptons and inert Higgs. Meanwhile, the model can give a better fit to the data of lepton universality in τ decays than the SM. Further, the multi-lepton event searches at the LHC impose a stringent upper bound on m_h, m_h< 35 GeV.
