Inert Model and evolution of the Universe

Abstract

We consider evolution of the Universe after EWSB leading to the present inert phase, containing a SM-like Higgs boson and scalar dark particles, among them a Dark Matter candidate. We address the question, if there is a possibility to have a sequence of the phase transitions instead of a single one leading directly from EW symmetric phase to the inert one.
