Decays of the Z′ boson to same-flavour light leptons ($e^+e^−$/$\mu^+\mu^−$) are studied for Z′ masses above 200 GeV. No significant excess over the Standard Model prediction is observed. The results of this search are interpreted for several dark-Higgs and light-vector benchmark model scenarios. Cross-section limits are set considering each benchmark scenario, as well as limits on the coupling of the Z′ with leptons.}, keywords = {talk (INSPIRE) / p p: scattering (INSPIRE) / p p: colliding beams (INSPIRE) / dark matter: hidden sector (INSPIRE) / Z': mass (INSPIRE) / Z': leptonic decay (INSPIRE) / Z': coupling (INSPIRE) / transverse energy: missing-energy (INSPIRE) / benchmark (INSPIRE) / vector boson: leptonic decay (INSPIRE) / lepton: pair production (INSPIRE) / electron: pair production (INSPIRE) / muon: pair production (INSPIRE) / ATLAS (INSPIRE) / new particle (INSPIRE) / new physics: search for (INSPIRE) / CERN LHC Coll (INSPIRE) / channel cross section: upper limit (INSPIRE) / coupling constant: upper limit (INSPIRE) / experimental results (INSPIRE) / 13000 GeV-cms (INSPIRE) / dark matter (autogen) / dark sector (autogen) / BSM resonance (autogen)}, cin = {ATLAS}, cid = {I:(DE-H253)ATLAS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF4-611)}, pid = {G:(DE-HGF)POF4-611}, experiment = {EXP:(DE-H253)LHC-Exp-ATLAS-20150101}, typ = {PUB:(DE-HGF)29}, doi = {10.3204/PUBDB-2023-07356}, url = {https://bib-pubdb1.desy.de/record/599368}, }
