The production of multiple Higgs bosons at the CERN LHC provides a direct way to measure the trilinear and quartic Higgs self-interaction strengths as well as potential access to beyond the standard model effects that can enhance production at large transverse momentum 𝑝T. The largest event fraction arises from the fully hadronic final state in which every Higgs boson decays to a bottom...
The discovery of the Higgs boson in 2012 was a triumph for the Standard Model (SM) of particle physics and the mechanism of electroweak symmetry breaking. An essential ingredient to this mechanism is the Higgs field potential, which is introduced ad-hoc and assumed to be Mexican-hat shaped in the SM, but cannot be derived from first principles. It is therefore important to probe this shape...
One of the central goals of the physics program at the future colliders is to elucidate the origin of electroweak symmetry breaking, including precision measurements of the Higgs sector. This includes a detailed study of Higgs boson pair production, which can reveal the Higgs self-interaction strength through the gluon fusion mode as well as the coupling between Higgs and vector bosons through...
The search for the HHH process at the LHC targets both the quartic and trilinear Higgs self-couplings, and thereby provides important information about the shape of the Higgs potential. Indirectly, it could also give insight in the matter-antimatter asymmetry observed in the universe. This presentation discusses the relation of the HHH process with the mechanism of electroweak symmetry...
