  • Abstract:

    After the discovery of the Higgs boson at the Large Hadron Collider (LHC), particle physicists have turned to the main outstanding issues in particle physics, two of which are: the CP-violation deficit in the Standard Model (SM) and the existence of Dark Matter (DM). Any extension of the SM needs to take these ingredients into account. New sources of CP-violation are needed in order to accommodate the observed predominance of matter over anti-matter in the Universe. Also, if DM comes in the form of a particle, we need to know which are the best candidates. This work focuses on extensions of the SM, designed to find models that match theory with experiment, and their tests at LHC and future colliders. In order to define the best search strategies a close collaboration with the experimental groups at CERN is fundamental to acquire sensitivity to all such models.
