Light Singlino Dark Matter at the LHC

Abstract

The light singlino-like 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(NMSSM).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, we present here, the detection prospect of such light DM candidate and Higgs bosons at the LHC.It is found that the range of Higgs bosons and neutralino masses compatible with a low mass DM solution can be discovered at the LHC with the center of mass energy s=14 TeV with a reasonable signal significance (∼ 5 σ ) corresponding to integrated luminosity options 300 and 3000 fb- 1.
