Searches for Supersymmetry (SUSY) in events with two opposite-sign same-flavour leptons offer sensitivity to the production of sleptons or Z bosons in the cascade decays of initially produced heavy SUSY particles. In the considered models, this signature is accompanied by the presence of several jets and high missing transverse energy. Analysing their respective datasets recorded at √ s = 8 TeV, the ATLAS and CMS collaborations previously reported deviations from the predicted Standard Model backgrounds in this final state, with significances between 2.6 and 3.0 σ . However, these excesses had been observed in different regions of the dilepton invariant mass. The dataset recorded with the CMS detector at √ s = 13 TeV in 2015, corresponding to 2.3 fb−1, offers the opportunity to substantiate or refute these interesting hints for new phenomena. Unfortunately, no significant deviation from the background estimates are observed in either of the two selections which had shown excesses in the √ s = 8 TeV datasets.
