dc.description.abstract We studied an extension of the standard model with a fourth generation of fermions to explain the discrepancy in the muon (g − 2) and explain the positron excess seen in the AMS-02 experiment. We introduce a gauged SU(2)HV horizontal symmetry between the muon and the 4th generation lepton families. The 4th generation right-handed neutrino is identified as the dark matter with mass 700 GeV. The dark matter annihilates only to (μ+μ−) and ( cμ μ) states via SU(2)HV gauge boson. The SU(2)HV gauge boson with mass 1.4 TeV gives an adequate contribution to the (g − 2) of muon and fulfill the experimental constraint from BNL measurement. The higgs production constraints from 4th generation fermions is evaded by extending the higgs sector. en_US
