Abstract

A search for high-mass resonances decaying to $τ ν$ using proton-proton collisions at $\sqrt{s} = 13 TeV$ produced by the Large Hadron Collider is presented. Only $τ$ -lepton decays with hadrons in the final state are considered. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of $36.1 {fb}^{- 1}$ . No statistically significant excess above the standard model expectation is observed; model-independent upper limits are set on the visible $τ ν$ production cross section. Heavy $W^{'}$ bosons with masses less than 3.7 TeV in the sequential standard model and masses less than 2.2–3.8 TeV depending on the coupling in the nonuniversal $G (221)$ model are excluded at the 95% credibility level.
