  1. 90. Higgs-boson production in top-quark fragmentation

  2. 63. New constraints on extended Higgs sectors from the trilinear Higgs coupling (10'+8')
    Johannes Braathen (DESY)
    28/11/2022, 09:00

    The trilinear Higgs coupling is a crucial tool to determine the structure of the Higgs potential and to probe possible effects of physics beyond the Standard Model (SM). Focusing on a Two-Higgs-Doublet Model as a concrete example, I will discuss the calculation of the dominant two-loop corrections to the trilinear Higgs coupling, and show that this coupling can be significantly enhanced with...

    Kay Schönwald (University of Zuerich)
    28/11/2022, 09:18

    Double Higgs production will be a key observable to probe the structure of the Higgs potential. In this talk I will present the first step in obtaining the electroweak corrections to double Higgs production by considering the leading Yukawa corrections to this process in the high energy limit. I will describe the methods we used and show that we obtain precise numerical results down to $p_T...

  9. 65. Triple Higgs production in the SM and in models with singlet NP scalars at proton-proton colliders (10'+8')
    Gilberto Tetlalmatzi-Xolocotzi (Siegen University)
    28/11/2022, 09:36

    In this talk we will discuss the production of three Higgs bosons in the LHC and at a proton-proton collider running at a centre-of-mass energy of 100 TeV. We will argue that the seemingly challenging 6-botton jets final state is a very good candidate to investigate triple Higgs production within and beyond the SM in proton-proton colliders. In particular we will consider three different...

    Kateryna Radchenko Serdula (DESY)
    28/11/2022, 09:54

    The dominant Higgs pair production process in the HL-LHC is gluon fusion, which we study in the framework of the Two Higgs Doublet Model. As a key observable we evaluate the invariant mass distribution of two Higgses at 125 GeV in the final state. We analyze in particular the contribution of the resonant diagram involving a heavy CP-even Higgs boson exchange. We analyze the potential...

    Botao Guo (Peking University (CN))
    28/11/2022, 10:12

    The Higgs boson pair production via gluon-gluon fusion and vector boson fusion in the bbμ+μ− final state at the LHC is studied to probe the Higgs self-coupling κλ and the four-boson HHVV coupling κ2V for the first time. A cut-based analysis and a machine learning analysis using boosted decision trees are performed with categorizations and optimizations depending on the variations of these...

    Benedict Tobias Winter (Albert Ludwigs Universitaet Freiburg (DE))
    28/11/2022, 11:00

    The current Simplified Template Cross-Section (STXS) categorization leaves STXS analyses insensitive to CP-odd contributions in Higgs boson production, which are predicted by several models beyond the Standard Model. This presentation proposes to categorize events with two jets additionally via the dPhijj observable to make future Run 2+3 analyses sensitive to CP violation. The feasibility of...
