Speaker: Alberto Salvio (University of Rome and INFN Tor Vergata)

The Standard Model of the strong and electroweak interactions (SM), together with Einstein’s general relativity (GR), is a very successful theory that explains all known interactions between observed particles, including the Higgs boson discovered in 2012. There is, however, no doubt that both the SM and GR need to be extended. I will review some of the most important arguments that show the necessity of extending this standard theory and mention some explicit extensions. I will also discuss what I think is a successful strategy for guessing the right path to go beyond such paradigm: designing models for a vast (possibly infinite) energy range, taking into account all observational bounds from both particle physics and astrophysics. One way to achieve this goal is to construct a viable and UV-complete relativistic field theory of all interactions, which I will illustrate at the end.
