Abstract:

We have searched for heavy neutral gauge bosons (Z') in p虅p collisions at s=1.8 TeV. The data were obtained using the CDF detector during the 1992-1993 run corresponding to an integrated luminosity of 19.7卤0.7 pb-1. We present a 95% confidence level upper limit on the production cross section times the branching ratio of Z' decaying into dielectrons as a function of Z' mass. Assuming standard model coupling strengths, we exclude a Z' with a mass less than 505 GeV/c2. We also present lower mass limits for Z' bosons from E6 models and the alternative left-right model.

Abstract:

We have used 19 pb-1 of data collected with the Collider Detector at Fermilab to search for new particles decaying to dijets. We exclude at 95% confidence level models containing the following new particles: axigluons with mass between 200 and 870 GeV/ c2, excited quarks with mass between 80 and 570 GeV/ c2, and color octet technirhos with mass between 320 and 480 GeV/ c2. 漏 1995 The American Physical Society.

Abstract:

We analyze a sample of W+jet events collected with the Collider Detector at Fermilab (CDF) in pp禄 collisions at s=1.8 TeV to study tt禄 production. We employ a simple kinematical variable H, defined as the scalar sum of the transverse energies of the lepton, neutrino, and jets. For events with a W boson and four or more jets, the shape of the H distribution deviates by 3.8 standard deviations from that expected from known backgrounds to tt禄 production. However, this distribution agrees well with a linear combination of background and tt禄 events, the agreement being best for a top mass of 180 GeV/c2. 漏 1995 The American Physical Society.
