Search for W′→eν and W′→μν in p¯p Collisions at s=1.8 TeV

The W′ is a charged, heavy, vector boson predicted to exist by some extensions of the standard model. We have searched for the processes W′→eν and W′→μν for ${\mathrm{M}}_{\mathrm{W}\prime }$>100 GeV/${\mathrm{c}}^2$, in p¯p collisions at s=1.8 TeV, using data taken with the Collider Detector at Fermilab. The nonobservation of these processes leads to a lower limit of 520 GeV/${\mathrm{c}}^2$ (95% confidence level) on the mass of the W′, assuming standard-strength couplings to three fermion generations.
