SU(2)SU(2) minimal dark matter with 2 TeV
We construct the minimal dark matter models in the left-right symmetric
extensions of the standard model (SM), where the gauge symmetry
SU(3)SU(2)SU(2)U(1) is broken into its
subgroup SU(3)U(1) by nonzero VEVs of a SU(2) doublet
and a SU(2) SU(2) bidoublet . A possible candidate of
dark matter is explored in the framework of minimal dark matter considering
SU(2) multiplet scalar bosons and fermions. Then we focus on SU(2)
quintuplet fermions with charges 0, 2 and 4 as the minimal dark matter
candidates and investigate phenomenology of them. We show that the dark matter
in the model can provide observed relic density with 2 TeV boson which is
motivated by the ATLAS diboson excess and CMS excess. The possible mass
of dark matter is predicted for each 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.Comment: 12 pages, 11 figures, version published in Phys. Lett.
