    Felix Egle
    07/04/2025, 15:30

    The next-to-minimal supersymmetric extension of the Standard Model (NMSSM) belongs to the most prominent, best motivated and experimentally widely tested beyond-SM extensions. For a meaningful interpretation of the experimental results and in order to be able to pin down the model underlying nature from the theory side, precise predictions for observables and parameters are crucial. Moreover,...

  4. 9. Effective Field Theories for Heavy Higgs Bosons in Standard Model Extensions
    Sebastian Schuhmacher
    07/04/2025, 17:00

    We integrate out the heavy scalar mass eigenstate in a real Higgs singlet extension of the Standard Model at one-loop order, taking into account full mixing and renormalization. We discuss the choice of a proper decoupling limit and matching of the result on SMEFT versus HEFT. Finally we validate convergence of predictions from the effective theory to the full result for a chosen set of...

  5. 7. Renormalization of the general Two-Higgs-Doublet Model
    Robin Feser
    08/04/2025, 09:00

    The Two-Higgs-Doublet Model (THDM) is one of the simplest and most extensively studied extensions of the Standard Model of particle physics (SM). It offers a rich phenomenology, and can, depending on the region in parameter space, address phenomena such as the observed matter-antimatter asymmetry in the universe and dark matter, which cannot be fully explained by the SM.\\ When computing...

  7. 11. Two-Loop Corrections to Trilinear Higgs Couplings in Higgs BSM models
    Alain Verduras Schaeidt (DESY)
    08/04/2025, 11:30

    The precise determination of the Higgs self-couplings is an essential task for understanding electroweak symmetry breaking and probing physics beyond the Standard Model (SM). The calculation of two-loop corrections is important to provide a critical test of the perturbative stability, especially in the case of large one-loop corrections that can occur in scenarios with extended scalar sectors....

  10. 13. Update on Higgs mass calculation with FlexibleEFTHiggs ( cancelled :( )
    Johannes Wünsche
    08/04/2025, 17:00

    FlexibleEFTHiggs is a hybrid method for the calculation of the SM-like Higgs mass in SUSY-models and is implemented in the spectrum generator FlexibleSUSY. This talk will include a recap of the method and some of its subtleties like the usage of the full-model parametrization in the calculation. The recent modifications of FlexibleEFTHiggs will be presented like the inclusion of 3-loop QCD...
