We compute the complete next-to-leading order SUSY-QCD corrections for the associated production of a charged Higgs boson with a top quark via bottom-gluon fusion. We investigate the applicability of the bottom parton description in detail. The higher order corrections can be split into real and virtual corrections for a general two Higgs doublet model and into additional massive supersymmetric loop contributions. We find that the perturbative behavior is well under control. The supersymmetric contributions consist of the universal bottom Yukawa coupling corrections and non-factorizable diagrams. Over most of the relevant supersymmetric parameter space the Yukawa coupling corrections are sizeable, while the remaining supersymmetric loop contributions are negligible.

    hep-ph 2026-07 accept novelty 7.0 of 10

    Signed neural control variates from normalizing flows, combined with neural importance sampling, reduce weight ranges and negative weights for LO and NLO phase-space integration and event generation.

  2. Charged Higgs Search in 2HDM

    hep-ph 2024-12 accept novelty 5.0 of 10

    Updated LHC and LEP constraints on charged Higgses show that H+ to A W and H+ to H W decay channels are complementary to fermionic channels and extend the search reach in the Type-L 2HDM.
