We present searches for quark-lepton compositeness and a heavy W' boson at high electron-neutrino transverse mass. We use similar to 110 pb(-1) of data collected in pp collisions at roots = 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 A, the ratio of partial cross sections sigma (W' --> e nu)/sigma (W --> 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(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(2) at the 95% confidence level.

Abstract

We present searches for quark-lepton compositeness and a heavy W' boson at high electron-neutrino transverse mass. We use similar to 110 pb(-1) of data collected in pp collisions at roots = 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 A, the ratio of partial cross sections sigma (W' --> e nu)/sigma (W --> 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(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(2) at the 95% confidence level.
