Abstract

Thanks to the latest development in the field of Monte Carlo event generators and satellite programs allowing for a straightforward implementation of any beyond the Standard Model theory in those tools, studying the property of any softly-broken supersymmetric theory is become an easy task. We illustrate this statement in the context of two non-minimal supersymmetric theories, namely the Minimal Supersymmetric Standard Model with R-parity violation and the Minimal R-symmetric Supersymmetric Standard Model and choose to probe interaction vertices involving a non-standard color structure and the sector of the top quark. We show how to efficiently implement these theories in the Mathematica package FeynRules and use its interfaces to Monte Carlo tools for phenomenological studies. For the latter, we employ the latest version of the MadGraph program.
