The authors list may be incomplete! AB - A search is presented for physics non-resonant new phenomena in dielectron and dimuon final states, originating from large extra spatial dimensions. The LHC proton-proton collision dataset collected by the ATLAS detector between 2015 and 2018 is analyzed, corresponding to a total integrated luminosity of up to 139 fb^-1 at p s = 13 TeV. The dilepton invariant mass spectrum is a discriminating variable. No significant deviations from the Standard Model expectation are observed. Lower limits are set on the string scale M_S between 6.6 TeV and 6.4 TeV at the 95 KW - p p: colliding beams (INSPIRE) KW - new physics: search for (INSPIRE) KW - scale: string (INSPIRE) KW - dimuon: final state (INSPIRE) KW - dilepton: final state (INSPIRE) KW - p p: scattering (INSPIRE) KW - muon: pair production (INSPIRE) KW - electron: pair production (INSPIRE) KW - space-time: higher-dimensional (INSPIRE) KW - dilepton: mass spectrum (INSPIRE) KW - mass spectrum: (electron positron) (INSPIRE) KW - mass spectrum: (muon+ muon-) (INSPIRE) KW - CERN LHC Coll (INSPIRE) KW - ATLAS (INSPIRE) KW - statistical analysis (INSPIRE) KW - lower limit (INSPIRE) KW - data analysis method (INSPIRE) KW - experimental results (INSPIRE) KW - 13000 GeV-cms (INSPIRE) KW - upper limit (INSPIRE) KW - Extra Dimensions (autogen) KW - Exotics (autogen) KW - Non-resonant (autogen) KW - Dilepton (autogen) KW - EXOTICS (autogen) LB - PUB:(DE-HGF)29 DO - DOI:10.3204/PUBDB-2021-05346 UR - https://bib-pubdb1.desy.de/record/472937 ER -
