Temperature evolution of physical parameters in the Inert Doublet Model

Understand

Inert Doublet Model is a minimal extension of the Standard Model with the second scalar doublet that may provide a Dark Matter candidate.

• In this paper we consider different variants of the evolution of the Universe after inflation, that lead towards the Inert phase today.
• We extend our previous analysis, in particular by discussing the co-existence of minima and providing numerical examples of the evolutions of the mass parameters for the different types of the history of the Universe.
• We take into account the existing constraints, including the relict density data.
