SU(2)L × SU(2)R minimal dark matter with 2 TeV W′

We construct the minimal dark matter models in the left–right symmetric extensions of the standard model (SM), where the gauge symmetry SU(3)C×SU(2)L×SU(2)R×U(1)B−LSU(3)C×SU(2)L×SU(2)R×U(1)B−L is broken into its subgroup SU(3)C×U(1)emSU(3)C×U(1)em by nonzero VEVs of a SU(2)RSU(2)R doublet HRHR and a SU(2)L×SU(2)RSU(2)L×SU(2)R bidoublet H  . A possible candidate of dark matter is explored in the framework of minimal dark matter considering SU(2)L,RSU(2)L,R multiplet scalar bosons and fermions. Then we focus on SU(2)RSU(2)R quintuplet fermions with B−LB−L charges 0, 2 and 4 as the minimal dark matter candidates and investigate their phenomenology. We show that the dark matter in the model can provide observed relic density with 2 TeV W′W′ boson which is motivated by the ATLAS diboson excess and CMS eejj   excess. The possible mass of dark matter is predicted for each B−LB−L charge. We then estimate the scattering cross section of dark matter with nucleon and production cross section of charged components in the quintuplets at the LHC.
