Abstract

We report the results of a search for a W′ boson produced in pp̅ collisions at a center-of-mass energy of 1.8 TeV using a 107 pb^-1 data sample recorded by the Collider Detector at Fermilab. We consider the decay channel W′→ μν_μ and search for anomalous production of high transverse mass μν_μ lepton pairs. We observe no excess of events above background and set limits on the rate of W′ boson production and decay relative to standard model W boson production and decay using a fit of the transverse mass distribution observed. If we assume standard model strength couplings of the W′ boson to quark and lepton pairs, we exclude a W′ boson with invariant mass less than 660 GeV/c² at 95% confidence level.
