Search for aW′Boson via the Decay ModeW′→μνμin 1.8 TeVpp¯Collisions

We report the results of a search for a ${W}^{\ensuremath{'}}$ boson produced in $p\overline{p}$ collisions at a center-of-mass energy of 1.8 TeV using a $107{\mathrm{pb}}^{\ensuremath{-}1}$ data sample recorded by the Collider Detector at Fermilab. We consider the decay channel ${W}^{\ensuremath{'}}\ensuremath{\rightarrow}\ensuremath{\mu}{\ensuremath{\nu}}_{\ensuremath{\mu}}$ and search for anomalous production of high transverse mass $\ensuremath{\mu}{\ensuremath{\nu}}_{\ensuremath{\mu}}$ lepton pairs. We observe no excess of events above background and set limits on the rate of ${W}^{\ensuremath{'}}$ 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 ${W}^{\ensuremath{'}}$ boson to quark and lepton pairs, we exclude a ${W}^{\ensuremath{'}}$ boson with invariant mass less than $660\mathrm{GeV}/{c}^{2}$ at $95%$ confidence level.
