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 AMS02 experiment We introduce a gauged SU2HV horizontal symmetry between the muon and the 4th generation lepton families The 4th generation righthanded neutrino is identified as the dark matter with mass ~ 700GeV The dark matter annihilates only to μ + μ − and ν μ C ν μ states via SU2HV gauge boson The SU2HV gauge boson with mass ~ 14 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 sectorThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
