Higgs Portals to Dark Matter and Extra Dimensions

Carena The Higgs boson discovery at the Large Hadron Collider (LHC) revealed a type of particle never seen before, but there are good reasons to suppose that it is not the only of its kind. The LHC has the power to find the Higgs heavier cousins, and to help us understand the Higgs boson’s true nature: Is it an elementary particle hinting towards a new fermion-boson symmetry or is it composite in a more sophisticated world with new strong forces that act as a portal to extra dimensions of space? The LHC could prove to be a factory for the dark matter that makes up to 85% of all the matter in the universe, and show us how the Higgs boson/s interact with dark matter. Even more challenging, LHC data could hint whether the Higgs play a fundamental role in creating the imbalance between matter and antimatter that triggered our existence. I will  discuss the role of particle physics  in providing answers for these tantalizing mysteries of nature.
