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 $R_p$ defined as  $R_p \begin{equation}  R_p  = (-1)^{(3B + L + 2S)}$ 2S)}  \end{equation}  where S, B, and L, are the spin, baryon, and lepton quantum numbers of the particle [LEP]. 

This paper describes a search for such a decay of the form:   $\widetilde{t}\overline{\widetilde{t}} \begin{equation}  \widetilde{t}\overline{\widetilde{t}}  \rightarrow \mu^+ \mu ^- b \overline{b}$ \overline{b}  \end{equation}  Since the signature of this decay resembles that of many common Standard Model vertices, various data-based background estimation techniques were implemented in conjunction with Monte Carlo simulations to obtain a number of expected events. For a detailed description of these techniques see section \ref{sect:eventSelection}.
