    Exploring the Higgs sector via multi-Higgs production searches is a main goal for run-3 and high-lumi LHC. Can these searches inform us about the electroweak phase transition and matter-antimatter asymmetry? We address this question in the context of the TRSM (Two-Real-Singlet Model), which has known benchmark points enhancing multi-Higgs production. We update the triple-Higgs production...

  5. 42. Effect of anomalous HHH and ZZHH couplings on the decay width of H→4l [remote]
    Biswajit Das (The Institute of Mathematical Sciences, Chennai)
    05/12/2024, 10:50

    Despite the discovery of the Higgs boson, the Higgs sector of the standard model is still not fully established. In particular, the self-couplings of the Higgs boson and its couplings with gauge bosons are still to be fully determined. We consider electroweak corrections to the processes H --> ve ve~ vm vm~ and H --> e+ e- mu+ mu-. The corrections depend on the HHH coupling. We investigate...

  6. 43. Double Higgs production in vector boson fusion at NLO QCD with anomalous couplings
    Jens Braun (KIT)
    05/12/2024, 11:10

    We present a calculation of the NLO QCD corrections to Higgs boson pair production in vector boson fusion, combined with the leading operators parametrising anomalous interactions in non-linear Effective Field Theory (HEFT). Based on our Monte Carlo implementation using GoSam+Whizard, we investigate the effects of anomalous Higgs couplings on various observables.

  7. 83. Multi-Higgs production from VBS in HEFT (15'+5')
    Javier Martínez Martín (Universidad Complutense de Madrid & IPARCOS)
    05/12/2024, 11:30

    We computed some results for vector boson scattering  in HEFT for the production of 2, 3 and 4 Higgs bosons. This results are updated after the latest results from both CMS and ATLAS for single and double Higgs production.
