Search for TeV-scale gravity signatures in high-mass final states with leptons and jets with the ATLAS detector at sqrt{s}=13 TeV

A search for evidence for physics beyond the Standard Model in the production of final states with at least one high transverse momentum charged lepton, and two additional high transverse momentum leptons or jets, is performed using 80 pb${}^{-1}$ of proton-proton collisions recorded by the ATLAS detector at the Large Hadron Collider in 2015 at $\sqrt s$ = 13 TeV. No excess of events beyond Standard Model expectations is observed. Exclusion limits are set for black hole models with six extra dimensions.
