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 higgs discovery].   However, with this answer comes more questions as phenomena such as the origin of dark matter remain unanswered, leading theorist to look for physics “beyond the Standard Model”.   Supersymmetry is such a theory that proposes an extension to spacetime 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 $R_p$  defined as $R_p = (-1)^{(3B + L + 2S)}$
