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 [], using 3.2 fb−1 of proton–proton collision data at [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' boson with lepton-flavour-violating couplings at 3.0, 2.7 and 2.6 TeV, and on the mass of a supersymmetric tau sneutrino with R-parity-violating couplings at 2.3, 2.2 and 1.9 TeV, for e[mu], e[tau] and [mu tau] final states, respectively. The results are also interpreted as limits on the threshold mass for quantum black hole production.
