We discuss the automatised calculation of the Higgs mass in renormalisable supersymmetric models with complex parameters at the two-loop level. Our setup is based on the public codes SARAH and SPheno, which can now compute the two-loop corrections to masses of all neutral scalars in such theories. The generic ansatz for these calculations and the handling of the `Goldstone Boson catastrophe' is described. It is shown that we find perfect agreement with other existing two-loop calculations performed in the DR-bar scheme. We also use the functionality to derive results for the MSSM and NMSSM not available before: the Higgs mass in the constrained version of the complex MSSM, and the impact of CP phases in the two-loop corrections beyond order alpha-strong alpha-top for the scale invariant NMSSM are briefly analysed.

    hep-ph 2025-05 conditional novelty 6.0 of 10

    A two-component dark matter model combining an inert scalar triplet with a pseudo-Goldstone singlet revives the sub-TeV triplet desert region and predicts gravitational waves detectable by LISA, BBO, and DECIGO.

    hep-ph 2019-09 conditional novelty 6.0 of 10

    In the MSSM with heavy SUSY particles and complex phases, the lightest Higgs mass can vary by up to about 20 GeV with the phase of the trilinear couplings, while its CP-odd admixture drops below 0.5% once the charged ...

  3. Full two-loop QCD corrections to the Higgs mass in the MSSM with heavy superpartners

    hep-ph 2019-08 accept novelty 6.0 of 10

    The two-loop QCD threshold corrections that mix strong and electroweak couplings in the MSSM Higgs-mass EFT calculation are computed for the first time, completing the two-loop QCD matching at the SUSY scale.
