Abstract:
We introduce a new scalar triplet to produce masses for leptons,which is different from that for the quark sector in the standard model(SM).The new neutral scalars can effectively decrease the deviation of the muon anomalous magnetic moment between the SM and the experimental measurements.The large ratio of Higgs to diphoton decay observed by LHC experiments,furthermore,can also be understood by the inclusion of the new physics enhancements induced by the new charged scalars.
