Search for aW′Boson Decaying to a Top and Bottom Quark Pair in 1.8 TeVpp¯Collisions

We report the results of a search for a $W^{\prime }$ boson produced in $p\overline{p}$ collisions at a center-of-mass energy of 1.8 TeV using a $106{\mathrm{p}\mathrm{b}}^{-1}$ data sample recorded by the Collider Detector at Fermilab. We observe no significant excess of events above background for a $W^{\prime }$ boson decaying to a top and bottom quark pair. In a model where this boson would mediate interactions involving a massive right-handed neutrino (${\nu }_R$) and have standard model strength couplings, we use these data to exclude a $W^{\prime }$ boson with mass between 225 and $536\mathrm{G}\mathrm{e}\mathrm{V}/c^2$ at 95% confidence level for $M_{W^{\prime }}\gg M_{{\nu }_R}$ and between 225 and $566\mathrm{G}\mathrm{e}\mathrm{V}/c^2$ at 95% confidence level for $M_{W^{\prime }}<M_{{\nu }_R}$.
