抄録

We present searches for quark-lepton compositeness and a heavy W′ boson at high electron-neutrino transverse mass. We use ∼110pb-1 of data collected in pp¯ collisions at √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 Λ, the ratio of partial cross sections σ(W′ → ev)/σ(W → ev), and the mass of a W′ boson with standard model couplings. We exclude Λ < 2.81 TeV and a W′ boson with mass below 754GeV/c2 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/c2 at the 95% confidence level.
