Search for High-Mass Resonances Decaying to $\tau \nu$ in $pp$ Collisions at $\sqrt{s}$ = 13 TeV with the ATLAS Detector

Abstract

A search for high-mass resonances decaying to $\tau \nu$ using proton-proton collisions at $\sqrt{s}$ = 13 TeV produced by the Large Hadron Collider is presented. Only $\tau$-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 $\tau \nu$ production cross section. Heavy $W^{\prime }$ 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 non-universal G(221) model are excluded at the 95% credibility level.
