Search for a W' boson decaying to a $\tau$ lepton and a neutrino in proton-proton collisions at $\sqrt{s} =$ 13 TeV

Understand

A search for a new high-mass resonance decaying to a tau lepton and a neutrino is reported.

• The analysis uses proton-proton collision data collected by the CMS experiment at the LHC at $\sqrt{s} =$ 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$.
• The search utilizes hadronically decaying tau leptons.
• No excess in the event yield is observed at high transverse masses of the $\tau$ and missing transverse momentum.
