We present a detailed study of the heavy flavor content in the W + jet data sample collected with the CDF detector during the 1992-1995 collider run at Fermilab. Rates of heavy flavor jets, identified via the observation of secondary vertices or semileptonic decays of b and c quarks, are in good agreement with a standard model simulation including production of the top quark. An exception is the number of events in which a single jet has both a secondary vertex and a semileptonic decay tag. In the W + 2,3 jet data, we expect 4.4 " 0.6 and we find 13 such events. The kinematic properties of this small sample of events are statistically difficult to reconcile with the simulation of standard model processes.

Download W+ Jets Production at the Fermilab Tevatron Book in PDF, ePub and Kindle
The production properties of jets in W events have been measured using (square root)s = 1.8 TeV pp collisions at the Fermilab Tevatron Collider. Experimental results from several CDF and D0 analyses are compared to leading-order and next-to-leading-order QCD predictions.

Download W/Z+ Jets Production at the Tevatron Book in PDF, ePub and Kindle
Both the D0 and CDF experiments at Fermilab Tevatron collider at[radical]s= 1.8 TeV have accumulated over 50pb[sup -1] of data. Each experiment collected more than 50,000 W[yields] l+v and 5000 Z[yields] l+[bar l] candidates for each lepton species (e and[mu]). Using this large data sample of W and Z candidates, the two experiments are actively testing perturbative QCD predictions. Among the studies that are in progress, preliminary results of W/Z+jets characteristics, multiplicity distributions of associated jets, and a study on the determination of the strong coupling constant using the ratio of the W+1 jet to W+ 0 jet cross sections are presented.

Download Jet Physics at the Tevatron Book in PDF, ePub and Kindle
Recent analyses by the CDF and D0 Collaborations of jet data produced in p{bar p} collisions at the Fermilab Tevatron Collider are presented. These include new studies of the inclusive jet production cross section, a measurement of the strong coupling constant, the first measurement of subjet multiplicity of quark and gluon jets, examination of ratios of multijet cross sections and their implications for choice of renormalization scale, and a study of charged jet evolution and energy flow in the underlying event. The results are compared to theoretical predictions.

Download Review of Recent Tevatron Jet, W Book in PDF, ePub and Kindle
This document reviews several recent measurements at the Fermilab Tevatron, including the cross sections of inclusive jet, dijet production, the cross sections of electroweak boson (W or Z) production in association with inclusive or heavy-flavor (b or c) jets, and b-jet shapes. In addition, searches for new physics using the dijet angular distributions are discussed. These analyses are based on integrated luminosities of 0.3--2.5/fb of p-{bar p} collisions at (square root)s = 1.96 TeV, collected with the CDF and D0 detectors. The results directly test the leading order and next-to leading order calculations of perturbative quantum chromodynamics and provide constraints on the parton distribution functions, gluon-splitting contribution, and physics beyond the standard model.
