Download Dijet Invariant Mass Spectrum at CDF. Book in PDF, Epub and Kindle
A summary of QCD results obtained using the dijet invariant mass spectrum d[sigma]/dM[sub jj] is presented. The spectrum is compared with QCD Leader Order and with the recently published Next to Leading Order calculations. A limit on the scale of an eventual quark compositness can be set at [Lambda]=1300 GeV. Limits on the production of new particles, decaying hadronically, are presented, too. Axigluons are ruled out in the mass range [240, 640] GeV, for a theory with N=10 strong interacting fermions, and in the two windows [260, 280] GeV and [450, 550] GeV, for N=20.

Download QCD Tests and New Physics Search with Jets at CDF. Book in PDF, Epub and Kindle
The dijet invariant mass spectrum at a center of mass energy √s = 1.8 TeV measured at the Tevatron Collider by CDF in the 1988--1989 run is presented. Comparison with leading order and next-to-leading order QCD theoretical calculation is performed. A search for a possible quark compositeness and for axigluons, while not showing evidence for new physics, allows one to put limits on the compositeness mass scale [Kappa]{sub c} and on the axigulon mass M{sub a}. Preliminary results for the inclusive jet and the total transverse energy cross section from the high statistics data collected in the present run are shown.

Download The Dijet Invariant Mass at the Tevatron Collider Book in PDF, Epub and Kindle
The differential cross section of the process p + pbar --> jet + jet + X as a function of the dijet invariant mass has been measured with the CDF detector at a center of mass energy of 1.8 TeV at the Tevatron Collider in Fermilab. The present analysis is based on the sample of events collected in the 1988/89 run, amounting to a total integrated luminosity of 4.2 pb−1. A comparison to leading order QCD and quark compositeness predictions is presented as well as a study of the sensitivity of the mass spectrum to the gluon radiation. 10 refs., 6 figs.

Download Jet Results from CDF. Book in PDF, Epub and Kindle
Recent results from CDF in jet physics are presented. Tests of leading order and next to leading order QCD are performed by measuring the dijet invariant mass spectrum, jet shapes and three jet events. Tests the leading logarithm, approximation in QCD are made by comparing the high energy events at CDF with the Herwig Monte Carlo. 10 refs., 7 figs.

Download Study of the Dijet Invariant Mass in W + 2 Jet Events Book in PDF, Epub and Kindle
The D0 Collaboration presents a study of the dijet invariant mass spectrum, M{sub jj}, in events with two jets produced in association with a W → l? boson. The goal is to verify a claim from the CDF Collaboration about the possible existence of an anomalous dijet resonance at M{sub jj} ≈ 145 GeV. Thus, we investigate the 110 GeV

Download Deep Inelastic Scattering Book in PDF, Epub and Kindle
These proceedings present the most up-to-date status of deep inelastic scattering (DIS) physics. Topics such as structure function measurements and phenomenology, quantum chromodynamics (QCD) studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in leptonproton scattering.

Download Techniques and Concepts of High-Energy Physics IX Book in PDF, Epub and Kindle
The ninth Advanced Study Institute (AS!) on Techniques and Concepts of High Energy Physics was almost canceled before ifbegan! A certain visitor to the area (Hurricane Bertha) arrived unexpectedly early in 1996. It was the first hur ricane in memory to menace the Caribbean in early July! Fortunately, it passed St. Croix several days before our meeting, and left very little damage. (The Altar ellis survived the eye of the storm in the in the British West Islands!) The meeting was held once again at the hotel on the Cay, on that spec of land in the harbor ofChrirtiansted, St. Croix, U. S. Virgin Islands. After the first two days of, at times, outrageous downpour, the 71 participants from 26 coun tries began to relax and enjoy the lectures and the lovely surroundings of the In stitute. The primary support for the meeting was provided by the ~cientific Affairs Division of the North Atlantic Treaty Organization (NATO). The ASI was cosponsored by the U. S. department of Energy, by the Fermi National Accelera tor Laboratory (Fermi-lab), by the U. S. National Science Foundation, and by the University of Rochester. In addition, the International Science Foundation con tributed to the support of a participant from Russia. As in the case of the previous ASIs, the scientific program was designed for advanced graduate students and recent Ph. D. recipients in experimental parti cle physics.
