Abstract

We study the implications of phenomenological processes on a two-singlet extension of the standard model that we introduced in a previous work to describe light cold dark matter. We look into the rare decays of Υ and B mesons, in particular, the invisible channels, and study the decay channels of the Higgs particle. Preferred regions of the parameter space are indicated, together with others that are excluded. We also comment on the recent Higgs search and findings at the LHC.

Note that in deriving the constraint on the invisible width of the simplest singlet dark matter model, the authors have used the older ATLAS and CMS analyses available at that time. Using the latest analysis [12,13] will rule out the possibility of opening up the Higgs window above 140 GeV in the one singlet model.
