These searches make use of proton--proton collision data, collected during 2015 and 2016 at a centre-of-mass energy $\\sqrt{s}=13$ TeV by the ATLAS detector at the Large Hadron Collider, which correspond to an integrated luminosity of 14.7 fb$^{-1}$. Both searches target the pair production of supersymmetric particles, squarks or gluinos, which decay to final states containing a same-flavour opposite-sign lepton pair via one of two mechanisms: a leptonically decaying Z boson in the final state, leading to a peak in the dilepton invariant-mass distribution around the Z boson mass; and decays of neutralinos (e.g. $\\tilde{\\chi}_2^0 \\rightarrow \\ell^+\\ell^- \\tilde{\\chi}_1^0$), yielding a kinematic endpoint in the dilepton invariant-mass spectrum. The data are found to be consistent with the Standard Model expectation. Results are interpreted in simplified models of gluino-pair (squark-pair) production, and provide sensitivity to gluinos (squarks) with masses as large as 1.70 TeV (980 GeV).","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.76903.v1/t1","@type":"Dataset","description":"Dilepton invariant mass distribution in SRZ.","name":"Table
