The extended BLMSSM with a 125 GeV Higgs boson and dark matter

Abstract

To extend the BLMSSM, we not only add exotic Higgs superfields $({\Phi }_{NL},{\phi }_{NL})$ to make the exotic lepton heavy, but also introduce the superfields($Y$,$Y^{\prime }$) having couplings with lepton and exotic lepton at tree level. The obtained model is called as EBLMSSM, which has difference from BLMSSM especially for the exotic slepton(lepton) and exotic sneutrino(neutrino). We deduce the mass matrices and the needed couplings in this model. To confine the parameter space, the Higgs boson mass $m_{h^0}$ and the processes $h^0\to \gamma \gamma$, $h^0\to VV,V=(Z,W)$ are studied in the EBLMSSM. With the assumed parameter space, we obtain reasonable numerical results according to data on Higgs from ATLAS and CMS. As a cold dark mater candidate, the relic density for the lightest mass eigenstate of $Y$ and $Y^{\prime }$ mixing is also studied.
