Abstract
A search is performed for a heavy particle decaying into different-flavor, dilepton pairs (, or ), using of proton-proton collision data at collected in 2015–2016 by the ATLAS detector at the Large Hadron Collider. No excesses over the Standard Model predictions are observed. Bayesian lower limits at the 95% credibility level are placed on the mass of a boson, the mass of a supersymmetric -sneutrino, and on the threshold mass for quantum black-hole production. For the and sneutrino models, upper cross-section limits are converted to upper limits on couplings, which are compared with similar limits from low-energy experiments and which are more stringent for the and modes.
