The SM-like Higgs Boson Mass in the CP-Violating High-Scale Next-to Minimal Supersymmetric Standard Model Open
In this report, we present a reliable prediction of the SM-like Higgs boson mass within the CP-violating next-to-minimal supersymmetric extension of the SM (NMSSM). We use an effective field theory framework together with two possible matc…

Higgs mass predictions in the CP-violating high-scale NMSSM Open
In a supersymmetric theory, large mass hierarchies can lead to large uncertainties in fixed-order calculations of the Standard Model (SM)-like Higgs mass. A reliable prediction is then obtained by performing the calculation in an effective…

NNLL-fast 2.0: Coloured sparticle production at the LHC run 3 with $\sqrt{S}$ = 13.6 TeV Open
We report on updated precision predictions for total cross sections of coloured supersymmetric particle production at the LHC with a centre-of-mass energy of \sqrt{S} = 13.6 TeV, computed with the modern PDF4LHC21 set. The cross sect…

Double and triple Higgs boson production to probe the electroweak phase transition Open
The production of three Higgs bosons could be a stretch goal for the LHC and a strategic case for future colliders. In this work, we analyse the phenomenological prospects of (neutral) triple Higgs compared to di-Higgs boson production, fo…

Intermediate charge-breaking phases and symmetry non-restoration in the 2-Higgs-Doublet Model Open
A bstract The Higgs potentials of extended Higgs sectors exhibit a complex and interesting vacuum structure. When travelling back in time, i.e. going to higher temperatures, the structure may change and exhibit interesting phase patterns a…

The trilinear Higgs self-couplings at $$\mathcal {O}(\alpha _t^2)$$ in the CP-violating NMSSM Open
In supersymmetric theories the Higgs boson masses are derived quantities where higher-order corrections have to be included in order to match the measured Higgs mass value at the precision of current experiments. Closely related through th…

Scalar leptoquarks at the LHC and flavour anomalies: a comparison of pair-production modes at NLO-QCD Open
We analyse scalar leptoquark pair production at the LHC with predictions including $t$-channel lepton exchange contributions up to next-to-leading order (NLO) in QCD. In particular, we calculate NLO-QCD predictions for off-diagonal product…
