Abstract:
Despite the successful structural completion of the Standard Model (SM) of particle physics through the discovery of the Higgs boson, questions remain open that cannot be answered within the SM. Among these, two of the most prominent ones are those for the nature of Dark Matter (DM) and why there is more matter than antimatter in the universe. Extended Higgs sectors beyond the SM have the potential to answer these questions in specific regions of their parameter space. So far, unfortunately, we do not have any direct sign of new physics. In this situation the role of the Higgs boson becomes extremely important as a dissection tool in our search for physics beyond the SM. I will highlight in my talk the special role of the Higgs boson and how it may guide our way in our quest for the model that allows us to describe nature and help us to understand the true picture behind it.
