Description
We consider an extension of the Standard Model by a singlet scalar that accounts for the dark matter of the Universe. Within this model we compute, for the first time, the expected gamma ray flux from the annihilation of dark matter particles. In addition, an updated analysis of the parameter space of the model is presented. By enforcing the relic density constraint from the very beginning, the viable parameter space gets reduced to just two variables: the singlet mass and the higgs mass. Current direct detection constraints are then found to require a singlet mass larger than 50 GeV. Finally, it is shown that, over most of the viable region, the continuum gamma ray signal lies within the sensitivity of GLAST.
