This analysis is based on data recorded  by the CMS experiment from proton-proton collisions at a center-of-mass energy of 13\\TeV at the LHC, corresponding to a total integrated luminosity of 138~\\fbinv. No significant deviation from the SM prediction is observed. Limits are set on the production cross section of a \\Wprime boson decaying into tau lepton plus neutrino. Lower limits are set on the mass of the sequential SM-like heavy charged vector boson and the mass of a quantum black hole. Upper limits are placed on the couplings of a new boson to the SM fermions. Constraints are put on a nonuniversal gauge interaction model and an effective field theory model. For the first time, upper limits on the cross section of $t$-channel leptoquark (LQ) exchange are presented and are translated into exclusion limits on the mass and coupling of LQs in this search channel; the sensitivity of this analysis reaches into the parameter space of LQ models that attempt to explain the anomalies observed in B-meson decays. The limits presented for the various interpretations are the most stringent to date.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.135472.v1/t1","@type":"Dataset","description":"The transverse mass distribution of $ au$ leptons and missing transverse momentum observed in the Run-2 data (black dots with...","name":"Mass distribution of the $\\tau_{h}+p_{T}^{miss}$ channel"},{"@id":"https://doi.org/10.17182/hepdata.135472.v1/t2","@type":"Dataset","description":"Bayesian upper exclusion limits at 95% CL on the product of the cross section and branching fraction of a W$\\prime$...","name":"SSM upper cross section limit"},{"@id":"https://doi.org/10.17182/hepdata.135472.v1/t3","@type":"Dataset","description":"Bayesian 95% CL model-independent upper limit on the product of signal cross sections and branching fraction for the $\\tau+\\nu$ decay...","name":"Model-independent upper cross section limit"},{"@id":"https://doi.org/10.17182/hepdata.135472.v1/t4","@type":"Dataset","description":"Bayesian upper exclusion limits on the ratio $g_{W'}/g_{W}$ for an SSM-like W$\\prime$ boson are shown.
