In a supersymmetric theory, large mass hierarchies can lead to large uncertainties in fixed-order calculations of the SM-like Higgs mass. A reliable prediction is then obtained by performing the calculation in an effective field theory (EFT) framework, involving the matching to the full supersymmetric theory at the high scale to include contributions from the heavy particles, and a subsequent...

It is common practice to study the phenomenology of extended Higgs sectors ad-hoc. This approach becomes much more convincing when the extension is required to address the fundamental puzzles of SM. We show that if CP violation originates from spontaneous symmetry breaking, an additional light Higgs doublet below about 500 GeV is needed, in the framework of minimal renormalizable SO(10). Its...

Despite being a mainstay in particle physics textbooks throughout several decades, the actual shape of the Higgs potential is rather loosely constrained. Soon, through the high luminosity phase of the LHC program, our field will get the possibility to examine one process in particular: Higgs pair production from gluon-gluon fusion. Measuring this in an unprecedented precision will allow to...

The virtual corrections for $gg \to HH$ at NLO QCD have been efficiently approximated using a Taylor expansion in the limit of a forward kinematics. The same method has been recently applied to the calculation of a subset of the NNLO corrections, which are desirable given the significant impact, at NLO, of the uncertainty due to the choice of the top mass renormalization scheme. In this talk,...
