| Summary: | A search for a new high-mass resonance decaying to a τ lepton and a neutrino is reported. The
analysis uses proton-proton collision data collected by the CMS experiment at the LHC at √s = 13 TeV,
corresponding to an integrated luminosity of 35.9 fb−1. The search utilizes hadronically decaying τ
leptons. No excess in the event yield is observed at high transverse masses of the τ and missing
transverse momentum. An interpretation of results within the sequential standard model excludes W
boson masses below 4.0 TeV at 95% confidence level. Existing limits are also improved on models in
which the W boson decays preferentially to fermions of the third generation. Heavy W bosons with
masses less than 1.7–3.9 TeV, depending on the coupling in the non-universal G(221) model, are excluded
at 95% confidence level. These are the most stringent limits on this model to date |
