Abstract: A search for Supersymmetry in events with opposite-sign same-flavour lepton pairs is presented. This final state, in addition to requirements on the number of jets and missing transverse energy, allows for a large reduction as well as a precise estimation of standard model backgrounds. In the cascade decays of new heavy particles, correlated production of leptons can lead to distinctive edges in the dilepton invariant mass spectrum, caused by the mass differences between the new particles. Presented is the search for such a mass edge in a dataset of pp collisions at $\sqrt{s}$ = 8\,TeV, corresponding to 19.4\,$\mathrm{fb}^{-1}$, collected with the CMS detector at the CERN LHC.
