The latest results on Higgs boson physics will be presented. The ATLAS and CMS collaborations have combined the Run 1 results on production and decay rates, deriving constraints on the standard model (SM) Higgs boson couplings. The first results from Run 2, including the decay channels into two photons, WW and ZZ, and associated top production, will be reported. Selected recent results...

Models of compositeness can successfully address the origin of the Higgs boson, as a pseudo-Goldstone of a spontaneously broken global symmetry, and flavour physics via the partial compositeness mechanism. If the dynamics is generated by a simple underlying theory defined in terms of a confining gauge group with fermionic matter content, there exists only a finite set of models that have the...

We re-investigate electroweak signal-background interference in associated Higgs production via gluon fusion in the presence of new physics in the top-Higgs sector. Considering the full final state pp → b b~ l+ l- (l=e,μ), we discuss how new physics in the top-Higgs sector that enhances the ZZ component can leave footprints in the HZ limit setting. In passing we study the phenomenology of a...

In the high-scale (split) MSSM, the measured Higgs mass sets an upper bound on the supersymmetric scalar mass scale $M_S$ around 10^10 (10^8) GeV, for tan beta in the standard range and the central value of the top mass. This work demonstrates that $M_S$ can be pushed up close to the Planck scale while reproducing a correct Higgs mass due to potentially large negative sbottom/stau threshold...

The Higgs-portal model, consisting in one singlet scalar particle coupled to the SM Higgs through renormalizable interactions is one of the most popular models for dark matter (DM). This model can easily reproduce the observed DM relic density, but it is strongly constrained by direct and indirect DM detection, as well as by collider physics. Actually, most of the parameter space is ruled-out...
