Several physics scenarios beyond the Standard Model predict the existence of new particles that can subsequently decay into a pair of Higgs bosons. This talk summarises ATLAS searches for resonant HH production with LHC Run 2 data. Several final states are considered, arising from various combinations of Higgs boson decays.
In this talk I will present the most recent CMS searches for heavy resonances decaying to HH and SH pairs. The S particle can be a standard model vector boson (W or Z) or a new scalar particle (Y) predicted in BSM models. Results from combination of different final states will be also shown.
In this talk, I will present an investigation into finite width and interference effects in di-Higgs production at the LHC, with a particular focus on the real Higgs singlet extension of the Standard Model. This extension enhances di-Higgs production through the resonant decays of an additional heavy scalar into two SM-like Higgs bosons. The study examines the impact of interference between...
In searches for beyond the Standard Model (BSM) Physics, bottom-up effective field theories (EFTs) such as the Standard Model EFT (SMEFT) and Higgs EFT (HEFT) have become crucial theoretical tools. Besides specifying their particle content and the respective symmetries on which the higher-dimensional operators are built, the choice of a power counting in a small parameter is the third...
