title = "Search for contact interactions and large extra dimensions in the dilepton channel using proton–proton collisions at √s=8 TeV with the ATLAS detector",
abstract = "A search is conducted for non-resonant new phenomena in dielectron and dimuon final states, originating from either contact interactions or large extra spatial dimensions. The LHC 2012 proton–proton collision dataset recorded by the ATLAS detector is used, corresponding to 20 fb(Formula presented.) (Formula presented.) at (Formula presented.) (Formula presented.)= 8 TeV. The dilepton invariant mass spectrum is a discriminating variable in both searches, with the contact interaction search additionally utilizing the dilepton forward-backward asymmetry. No significant deviations from the Standard Model expectation are observed. Lower limits are set on the (Formula presented.) (Formula presented.) contact interaction scale (Formula presented.) (Formula presented.) between 15.4 TeV and 26.3 TeV, at the 95 % credibility level. For large extra spatial dimensions, lower limits are set on the string scale (Formula presented.) (Formula presented.) between 3.2 TeV to 5.0 TeV.",
