Description

A broad class of theoretical scenarios called “the Higgs-portal models” describes the interaction of dark matter with the “usual” matter only through the Higgs sector. From an experimental point of view, the models provide an interesting intersection of several directions in the search for new physics, namely, the study of non-standard properties of the observed Higgs boson, the search for new Higgs states from the extended Higgs sector and the search for new particles - candidates for dark matter. The talk presents the recent results of the CMS collaboration on this topic.
