Characterizing the Higgs potential at the LHC and future colliders
The characterization of the Higgs potential has become, in the past few years, one of the main focuses of the high-energy particle physics community, both from the theoretical and experimental side, due to the role of potential in the mechanism of EW symmetry breaking, and in order to have a better understanding of the EW phase transition in the early universe.
Colliders are the main tools at our disposal to probe the structure of the potential (at the EW scale), by allowing the determination of the self couplings of the Higgs boson in an experimental settings.
In this talk I will review the current status of the related physics program at the LHC, and at future colliders, highlighting the important connection between theory and experiments required by these measurements.
Moreover, I will present a couple of interesting BSM scenarios that could be probed at these machines.
Finally, I will also highlight the connection between the measurement of the trilinear Higgs self coupling, a strong first order EW phase transition in the early universe, and signals at the LISA GW observatory.
