Abstract: (Springer)
A search is performed for a heavy particle decaying into different flavour dilepton pairs ( eμe\mu , eτe\tau or μτ\mu \tau ), using 3.2 fb−1^{-1} of proton–proton collision data at s=13\sqrt{s}=13  TeV collected in 2015 by the ATLAS detector at the Large Hadron Collider. No excess over the Standard Model prediction is observed. Limits at the 95 % credibility level are set on the mass of a Z′Z^\prime boson with lepton-flavour-violating couplings at 3.0, 2.7 and 2.6 TeV, and on the mass of a supersymmetric τ\tau sneutrino with R-parity-violating couplings at 2.3, 2.2 and 1.9 TeV, for eμe\mu , eτe\tau and μτ\mu \tau final states, respectively. The results are also interpreted as limits on the threshold mass for quantum black hole production.
