A search for high-mass resonances decaying into a τ-lepton and a neutrino using proton-proton
collisions at a center-of-mass energy of
ffiffiffi
ps ¼ 13 TeV is presented. The full run 2 data sample
corresponding to an integrated luminosity of 139 fb−1 recorded by the ATLAS experiment in the years
2015–2018 is analyzed. The τ-lepton is reconstructed in its hadronic decay modes and the total transverse
momentum carried out by neutrinos is inferred from the reconstructed missing transverse momentum. The
search for new physics is performed on the transverse mass between the τ-lepton and the missing transverse
momentum. No excess of events above the Standard Model expectation is observed and upper exclusion
limits are set on the W0 → τν production cross section. Heavy W0 vector bosons with masses up to 5.0 TeV
are excluded at 95% confidence level, assuming that they have the same couplings as the Standard Model
W boson. For nonuniversal couplings, W0 bosons are excluded for masses less than 3.5–5.0 TeV, depending
on the model parameters. In addition, model-independent limits on the visible cross section times branching
ratio are determined as a function of the lower threshold on the transverse mass of the τ-lepton and missing
transverse momentum.
