摘要：

report the results of a search for a W' boson produced in p (p) over bar 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' --> mu nu(mu), and search for anomalous production of high transverse mass py, 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 abt 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/c(2) at 95% confidence level.
