  3. 8. Precision predictions of partial decay widths in the general Two-Higgs-Doublet Model
    Jose Angel Hernandez Cuevas (Universität Freiburg)
    23/03/2026, 16:45

    The Standard Model (SM) of particle physics has achieved remarkable success in describing a broad spectrum of experimentally observed phenomena in particle physics with high precision. However, there are still some phenomena that lie beyond its description, such as the existence of dark matter, the matter-antimatter asymmetry of the universe, and the origin of neutrino masses. Several...

  5. 10. Two-Loop Pole-Mass Matching in the CP-Violating NMSSM

  6. 11. On-shell Renormalisation of Vector-like Lepton Models
    Kilian Möhling (IKTP TU Dresden)
    24/03/2026, 11:00

    Vector-like leptons are a special class of SM extensions with strong impact on the tree-level mass generation, the lepton--Higgs interaction as well as precision observables like g-2 or CLFV decays, and therefore nicely complement studies of EW BSM scenarios with extended Higgs sectors. The strong LO correlations motivate the inclusion of higher order corrections which, however, come with...

  7. 12. Sensitivity to New Physics in Higgs Observables
    Kateryna Radchenko Serdula (IFT)
    24/03/2026, 12:00

    Precision measurements of Higgs interactions provide one of the most powerful avenues to probe physics beyond the Standard Model (SM). In this talk, I will present automated one-loop calculations of the Higgs trilinear self-coupling and the $hZZ$ coupling within the Two Higgs Doublet Model (THDM) framework. This analysis is particularly relevant in view of future experimental facilities, where...

  8. 13. Renormalisation of Chiral Gauge Theories with Non-Anticommuting $\gamma_5$ at the Multi-Loop Level
    Dr Matthias Weisswange (DESY)
    24/03/2026, 15:00

    The computation of high-precision electroweak observables is of growing importance to meet the stringent requirements of current and future experiments and to probe physics beyond the Standard Model (SM). Such computations inevitably encounter the $\gamma_5$-problem. The Breitenlohner-Maison/'t~Hooft-Veltman (BMHV) scheme provides the only known framework for treating $\gamma_5$ in dimensional...

  9. 14. Infrared divergences and the choice of regularization
    Dr Wojciech Kotlarski (National Centre for Nuclear Research)
    24/03/2026, 16:00

    We discuss the treatment of infrared divergences when computing observables in the MSbar scheme, using the decay of Higgs to qqbar as an example.

  10. 15. NLO Calculation of the Process $h \to f \bar{f}$ in the Decoupling Renormalization Scheme
    Johannes Wünsche (TU Dresden, IKTP), Jonas Lang (National Center for Nuclear Research Poland)
    24/03/2026, 17:30

    We propose a decoupling renormalization scheme for use in the calculation of Higgs decays in BSM models, including models with extended Higgs sector, at NLO order. The calculation is implemented withing the FlexibleSUSY spectrum-generator generator. The current status of the work will be presented including a discussion of the decoupling limit, various subtleties of the scheme’s definition...
