Search for new phenomena in different-flavour high-mass dilepton final states in pp collisions at s√=13 Tev with the ATLAS detector

Abstract

A search is performed for a heavy particle decaying into different√ flavour dilepton pairs(eμ, eτ or μτ), using 3.2 fb −1 of proton-proton collision data at s = 13 TeV collected in2015 by the ATLAS detector at the Large Hadron Collider. No excess over the StandardModel prediction is observed. Limits at the 95% credibility level are set on the mass of aZ 0 boson with lepton-flavour-violating couplings at 3.0, 2.7 and 2.6 TeV, and on the massof a supersymmetric τ sneutrino with R-parity-violating couplings at 2.3, 2.2 and 1.9 TeV,for eμ, eτ and μτ final states, respectively. The results are also interpreted as limits on thethreshold mass for quantum black hole production.
