Light dark matter in a minimal extension with two additional real singlets
Markos Maniatis
Abstract:The direct searches for heavy scalar Dark Matter with a mass of order 100 GeV are much more sensitive than for light Dark Matter of order 1 GeV. The question arises whether Dark Matter could be light and has escaped detection so far. We study a simple extension of the Standard Model with two additional real singlets. We show that this simple extension may provide the observed relic Dark Matter density, does not disturb Big-Bang nucleosynthesis nor the Cosmic Microwave Radiation observations and fulfills the co… Show more
