A search for R-parity violating Supersymmetric top decays at CMS with \(\sqrt{s} = 8\) TeV

Abstract

A search for a supersymmetric top decay assuming a 100% branching ratio of \(\widetilde{t}\widetilde{t}^* \rightarrow \mu^+ \mu ^- b \overline{b}\) is presented using a minimally supersymmetric model at an integrated luminosity of \(19.5\ \mathrm{fb}^{-1}\). The datasets were recorded with the CMS detector at the LHC. Using Baysian marginalization, an upper limit on the cross section of this process is computed and a cut off point is calculated below which the data does not support the presence of the target decay. This cut off point was calculated to be around 780 GeV.
