Description

A search for Supersymmetry in opposite-sign same-flavour lepton pairs is presented. This final state, in addition with 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 difference of the new particles. Presented is the search for such an mass edge in a dataset of pp collisions at sqrt(s) = 8 TeV, corresponding to 19.4/fb, collected with the CMS detector at the CERN LHC.
