Abstract
We present searches for quark-lepton compositeness and a heavy boson at high electron-neutrino transverse mass. We use of data collected in collisions at by the CDF Collaboration during 1992–1995. The data are consistent with standard model expectations. Limits are set on the quark-lepton compositeness scale , the ratio of partial cross sections , and the mass of a boson with standard model couplings. We exclude and a boson with mass below at the confidence level. Combining with our previously published limit obtained using the muon channel, we exclude a boson with mass below at the confidence level.
