We analyze the Minimal Supersymmetric extension of the Standard Model that we have after the discovery of the Higgs boson at the LHC, the hMSSM (habemus MSSM?), i.e. a model in which the lighter h boson has a mass of approximately 125 GeV which, together with the non-observation of superparticles at the LHC, indicates that the SUSY-breaking scale MS is rather high, MS ≳1 TeV. We first demonstra...

We study a subset of electroweak-precision observables consisting of MW , sin 2 θ eff, BR(Z → τ τ) and Γ(Z → ττ)/Γ(Z → ee)− 1 (characterizing leptonic Z-decays) in the context of the NMSSM. After a brief review of common MSSM-NMSSM effects (e.g. for Γ(Z → ττ)/Γ(Z → ee)− 1, which has been little discussed, even in the MSSM), specific NMSSM scenarios are studied, with the result that the NMSSM, c...

Experimental collaborations for the large hadron collider conducted various searches supersymmetry. In absence of signals, lower limits were put on sparticle masses but usually within frameworks with (over-)simplifications relative to entire indications by supersymmetry models. For complementing current interpretations experimental bounds, we introduce a 30-parameter version R-parity conserving...

We present an overview of searches for MSSM Higgs at the Tevatron, concentrating on searches probing the high tanβ region. We discuss the search for A/H → ττ which is soon to be completed in the Run I data and review the new tau triggers implemented by CDF and D0 in Run II, which will greatly impact this analysis. We also present the results of a Run I search for A/Hbb→ bbbb performed by CDF an...

Recent results on two–loop calculations in the MSSM are reviewed. The computation of the QCD corrections to ∆ρ, ∆r and to the mass of the lightest Higgs boson in the MSSM are presented.

In order to achieve gauge unification at the string scale M X ∼ 5 × 10 17 GeV in the minimal supersymmetric standard model (MSSM) it is necessary to add extra gauge non-singlet representations at an intermediate scale M I < M X , leading to a class of models which we refer to as MSSM+X models. We perform a detailed analysis of a large class of MSSM+X models and find that the number of (3,1) rep...

The minimal supersymmetric extension of the Standard Model (MSSM) is reviewed. In the most general framework with minimal field content and R-parity conservation, the MSSM is a 124-parameter model (henceforth called MSSM-124). An acceptable phenomenology occurs only at exceptional points (and small perturbations around these points) of MSSM-124 parameter space. Among the topics addressed in thi...
