Light singlino dark matter at the LHC

The light singlinolike neutralino is expected to be a promising candidate for dark matter (DM) in the allowed parameter space of the next-to-minimal supersymmetric standard model. The DM annihilation process takes place via the light Higgs bosons which are natural in this model. Identifying the allowed region of parameter space including various constraints, the detection prospect of such light DM candidate and Higgs bosons are explored at the LHC with its high luminosity options. Light Higgs bosons and the DM candidate, the lightest singlinolike neutralino are indirectly produced at the LHC via the SM Higgs production and its subsequent decays. Jet substructure techniques are used to tag boosted Higgs. It is found that the favorable range of masses of Higgs bosons and neutralino, compatible with a low mass DM solution, can be discovered with a reasonable signal significance (similar to 5 sigma) at the LHC, with the center of mass energy root s = 14 TeV and integrated luminosity options L = 300 fb(-1) and 3000 fb(-1).
