We study the hadronic production of strongly interacting SUSY particles (top-squark pairs, gluino-squark pairs, and same sign squark-squark pairs) in the framework of the MSSM. Aiming at precise theoretical predictions, we calculate the cross section contributions of electroweak origin up to the one-loop level. We find sizable effects both from electroweak tree-level subprocesses and next-to-leading order corrections, reaching the 20% level in kinematical distributions.
In a second part of this thesis, we investigate the phenomenology of R-parity violating SUSY models with the lightest tau-slepton being the lightest SUSY particle (LSP). We analyze the possible LSP decay modes, taking into account the dynamical generation of non-zero R-parity violating couplings at lower scales. As an application of our studies which is interesting for experiments at particle accelators, we discuss single slepton production at the LHC.
