Search for Quark-Lepton compositeness and a heavy W' boson using the e{nu} channel in p{ovr p} collisions at {radical}{ovr s} = 1.8 TeV.
We present searches for quark-lepton compositeness and a heavy W' boson at high electron-neutrino transverse mass. We use {approx}110 pb{sup -1} of data collected in p{bar p} collisions at sqrt[s] = 1.8 TeV by the CDF Collaboration during 1992-1995. The data are consistent with standard model expectations. Limits are set on the quark-lepton compositeness scale {Lambda}, the ratio of partial cross sections {sigma}(W'{yields}e{nu})/{sigma}(W{yields}e{nu}), and the mass of a W' boson with standard model couplings. We exclude {Lambda}<2.81 TeV and a W' boson with mass below 754 GeV/c{sup 2} at the 95% confidence level. Combining with our previously published limit obtained using the muon channel, we exclude a W' boson with mass below 786 GeV/c{sup 2} at the 95% confidence level.
