ABSTRACT

In this work we explore the intermediate dark matter mass regime of 400-550 GeV in a mixed scalar dark mater (DM) model. This mass region remains suppressed from dark matter relic abundance observations. In this model, the standard model (SM) is extended by a scalar singlet and an inert doublet field. The lightest neutral Higgs that comprises of the CP-even component of inert doublet and a singlet scalar is the dark matter candidate. We scan over the parameter space consistent with theoretical and latest experimental constraints, as well as dark matter relic abundance and recent searches from experiment like XENON1T. We find that correct relic abundance for the intermediate mass region 400 < ?????? < 550 GeV could be revived by considering the mixed scalar dark matter model with appropriate couplings and mixings. Keywords: Dark matter, beyond standard model, XENON1T, Inert doublet, relic density
