The analysis uses proton-proton collision data collected by the CMS experiment at the LHC at s=13TeV, corresponding to an integrated luminosity of 35.9fb ?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. ? 2019 The Author(s)journal article10.1016/j.physletb.2019.01.0692-s2.0-85063392269
