The ATLAS and CMS experiments have recently published searches for supersymmetry in final states containing a same-flavour opposite-sign lepton pair, jets and missing transverse momentum. Two production mechanisms are considered: neutralino decays resulting in a kinematic edge in the dilepton invariant mass distribution; and decays of neutralinos with Z bosons in the final state, resulting in an invariant mass peak around the Z-boson mass. For the former, an excess of 2.6 \sigma is observed by CMS with respect to the SM expectation. For the latter, ATLAS reports a 3 \sigma excess. Here we discuss the analyses and results reported by both experiments.
