With the discovery of the Higgs, the Standard Model seems to offer a complete tally of the fundamental particles with which all of the matter around us is made \cite{Aad_2012}. However, with this answer comes more questions as phenomena such as the origin of dark matter remain unanswered, and cause theorists to look for physics beyond the Standard Model.   Supersymmetry is one such theory and proposes an extension to spacetime space-time  which allows for a symmetry relating the two groups of fundamental particles: fermions and bosons. Associated with this extension is a quantum number $R_p$ defined as \begin{equation}  R_p = (-1)^{(3B + L + 2S)}
