Constraints On The Charged Higgs Bosons From The 221 LFNU Model

The SU(2)1×SU(2)2×U(1)Y model with lepton-flavor non-universality called the 221 LFNU model,the model consists of an extended gauge group SU(2)1 ×SU(2)2× U(1)Y which breaks spontaneously around the TeV scale to the electroweak gauge group.Fermion mix-ing effects with vector-like fermions give rise to potentially large new physics contributions in flavour change process mediated by W’ and Z’ bosons.This model can ease tensions in B-physics data while satisfying stringent bounds from flavour physics,and electroweak precision data.The neutrino oscillation experiment shows that neutrinos have a tiny mass and can be mixed between different flavors,which means that the flavor numbers of lepton are not con-served.We take the phenomenon that the flavor numbers of lepton are not conserved before and after this reaction called lepton flavor violation.Due to the small mass of neutrinos,the process of violating the flavor of lepton is strongly suppressed.The LFV process has great potential to detect new physics on the energy scale much higher than TeV.The latest research conducted in different new physics scenarios found that there is an interesting correlation be-tween the LFV decay of Lepton μ and the LFV decay of Lepton τ.Corrected 221 LFNU model can generate the active neutrino masses via Zee mechanism,which predicts the existence of the charged Higgs bosons H2±.We consider their contributions to the decays μ→(?),μ→eγand(?)with l=e and μ and compare the numerical results with the measured values,the individual constraints on the factor |fij|/Mh are obtained.Their contributions to the muon g-2 and non-standard interactions(NSI)of neutrinos are also discussed.
