At the LHC one of the major production channels of neutral Higgs bosons
is gluon fusion. The process is loop-induced where the coupling of the
gluons to the Higgs bosons is mediated by heavy quark and squark loops.
Higher order QCD contributions have turned out to be large. Recently, the
full supersymmetric QCD corrections at next-to-leading order have been
obtained including the full...

We study extensions of the Minimal Supersymmetric Standard Model (MSSM) with new degrees of freedom that couple sizably to the MSSM Higgs sector and lie in the TeV range. After integrating out the physics at the TeV scale, the resulting Higgs spectrum can significantly differ from typical supersymmetric sce- narios, thereby providing a window Beyond the MSSM (BMSSM). Taking into account...

HFOLD (Higgs Full One-Loop Decays) is the first public available program which calculates all MSSM Higgs two-body decays at full one-loop level. The renormalization is done in the DRbar scheme following the SPA convention. The program is easy to use and supports Les Houches in- and output format. We compare the numerical results from HFOLD with some other public available programs. Particular...

We study the potential to observe CP-violating effects in top squark cascade decay chains at the LHC. Asymmetries composed by triple products of momenta of the final state particles are sensitive to CP-violating effects. Due to large boosts that dilute the asymmetries, these can be difficult to observe. If all particle masses in a cascade decay are known, it may be possible to reconstruct the...

If Supersymmetry (SUSY) exists in nature, the LHC might find first evidence for it within the next few years. After new physics phenomena are discovered, there will be many proposed explanations including supersymmetric models that will be consistent with the initial discovery. It is critical to identify observables that can provide direct evidence for an underlying supersymmetric...

Certain supersymmetric grand unified models predict that the coefficients of the quadratic terms in the MSSM Higgs potential should be degenerate at the GUT scale. We discuss some examples for such models, and we analyse the implications of this peculiar condition of a GUT-scale degenerate Higgs mass matrix for low-scale MSSM phenomenology. To this end we explore the parameter space which is...
