CDF Papers: Results from the Analysis of Events with Large Total Transverse Energy

Multijet events at the Tevatron Proton-Antiproton Collider

  • S. Geer, Talk given at the 10th Topical Workshop on Proton-Antiproton Collider Physics, Fermilab, Batavia, IL - May 9-13, 1995.
  • ABSTRACT: The characteristics of three-jet, four-jet, and five-jet events observed by the CDF and D0 experiments at the Fermilab Tevatron proton-antiproton collider are compared with leading order QCD matrix element predictions, and with the predictions from a parton shower Monte Carlo program.

    Properties of high-mass multijet events at the Fermilab proton-antiproton collider

  • F. Abe et al (CDF Collaboration), Phys. Rev. Lett. 75, 608 (1995).
  • ABSTRACT: The properties of two-, three-, four-, five-, and six-jet events with multijet masses > 600 GeV/c^2 are compared with QCD predictions. The shapes of the multijet-mass and leading-jet-angular distributions are approximately independent of jet multiplicity and are well described by the NJETS matrix element calculation and the HERWIG parton shower Monte Carlo predictions. The observed jet transverse momentum distributions for three- and four-jet events discriminate between the matrix element and parton shower predictions, the data favoring the matrix element calculation.

    A Study of the Events with the Highest Total Transverse Energy in CDF

  • E. Buckley-Geer (CDF Collaboration), Proceedings of the International Symposium on Lepton and Photon Interactions, Cornell University, Ithaca, NY, August 10-15, 1993.
  • ABSTRACT: The properties of proton-antiproton interactions in which the total transverse energy exceeds 320 GeV are described. The events have been recorded at the Fermilab Tevatron collider operating at a center-of-mass energy of 1.8 TeV. The differential cross-section is in good agreement with the QCD predictions.

    Properties of events with large total transverse energy produced in proton-antiproton collisions at SQRT(s) = 1.8 TeV

  • S. Geer (CDF Collaboration), Proceedings of the VIIth International Symposium on Very High Energy Cosmic-Ray Interactions, Ann Arbor, MI, June 21-27, 1992, p.258.
  • ABSTRACT: The properties of proton-antiproton interactions in which the total transverse enenergy exceeds 400 GeV are described. These events have been recorded at the Fermilab Tevatron collider operating at a center-of-mass energy of 1.8 TeV. The differential cross section, jet rates, jet transverse-momentum and pseudorapidity distributions, single-jet shapes, and the multijet rates and kinematics are compared with QCD predictions.

    Properties of events with large total transverse energy produced in proton-antiproton collisions at SQRT(s) = 1.8 TeV

  • F. Abe et al (CDF Collaboration), Phys. ReV. D45, 2249 (1992).
  • ABSTRACT: The properties of proton-antiproton interactions in which the total transverse enenergy exceeds 400 GeV are described. These events have been recorded at the Fermilab Tevatron collider operating at a center-of-mass energy of 1.8 TeV. The differential cross section, jet rates, jet transverse-momentum and pseudorapidity distributions, single-jet shapes, and the multijet rates and kinematics are compared with QCD predictions. There is no evidence for a significant deviation from standard-model expectations that would be signaled by the presence of an excess of isolated high-transverse-momentum leptons or photons, or am excess of events with unusual jet rates or characteristics.
