Minimal Supersymmetric Standard Model with R-parity violation (RPVMSSM) contributes to the neutron beta decay via Scalar, Pseudoscalar and CP-odd vector, axial vector interactions which are absent in the Standard Model. We discuss the contribution of the RPVMSSM to the angular correlations of the neutron beta decay at the one-loop level.

We present a calculation of the two-loop bottom-sbottom-gluino contributions to Higgs boson production via gluon fusion in the MSSM. The calculation is based on an asymptotic expansion in the masses of
the supersymmetric particles, which are assumed to be much heavier than the bottom quark and the Higgs bosons.
We obtain explicit analytic results that allow for a straightforward...

The effective bottom Yukawa couplings are analyzed for the minimal supersymmetric extension of the Standard Model at two-loop accuracy within SUSY-QCD. They include the resummation of the dominant corrections for large values of tg(beta). In particular the two-loop SUSY-QCD corrections to the leading SUSY-QCD and top-induced SUSY-electroweak contributions are addressed. The residual...

Direct Production of squarks and gluinos is one of the most important SUSY
discovery channels at the LHC.
After a brief review of the processes leading to the
production of such particles, I will present
the tree-level and next-to-leading order EW contributions.
The numerical
impact of these contributions in the case of squark-squark,
squark--anti-squark, squark-gluino,...

We propose an effective description of squark interactions with charginos/neutralinos. We recompute the strong corrections to squark partial decay widths, and compare the full one-loop computation with the effective description. The effective description includes the effective Yukawa couplings, and another logarithmic term which encodes the supersymmetry-breaking. The proposed effective...

We show that electroweak contributions can enhance the QCD squark pair cross section up to 50% at the LHC. We also discuss how electroweak contributions lead to rapidity gap events in squark pair production and in the end we discuss how we can obtain information on the coupling between a chargino, stop and bottom.
