Abstract

A heuristic model is used to describe data collected by the UA2 experiment at √s = 630 GeV. Distributions of the energy sharing between the leading clusters and the rest of the event are examined. The main features of these distributions can be described by a two-component model with soft, collective interactions dominating at low transverse energy and hard, constituent interactions dominating at high transverse energy. This model provides a simple picture of the emergence of two-jet dominance at SPS $p$ p Collider energies.

Physics with matter-antimatter colliders
1988, Physics Reports
This report provides an overview of experimental results obtained at electron-positron and proton-antiproton colliders, of the still unsolved problems, and of the prospects for their solution and for exploring new domains of physics with future colliders.
We first make some general remarks about the properties of detectors and colliders (section 1); we recall the results obtained with e⁺ e⁻ colliders, paying special attention to recent results and unsolved problems (section 2); we describe results obtained from 1980 to 1988 with pp̄ colliders (section 3); we review the expectations with future e⁺ e⁻ colliders (LEP, SLC, …) and proton-antiproton colliders (section 4); we describe briefly some of the properties of colliders with special attention to the possibilities of obtaining higher luminosity (section 5); and conclude with a brief recapitulation and some thoughts (section 6) about the next generation of high energy and high intensity colliders.
Production of low transverse energy clusters in pp collisions at √s=0.2-0.9 TeV and their interpretation in terms of QCD jets
1988, Nuclear Physics, Section B
The production of transverse energy clusters in minimum bias proton-antiproton collisions at the CERN SPS Collider is studied with the UA1 detector over a new range of centre of mass energies (√s = 0.2−0.9 TeV). This study is intended to investigate how low in transverse momentum perturbative QCD is able to describe the dynamics of hadron collisions. We observe that clusters with transverse energy in excess of a few GeV exhibit properties in agreement with QCD expectations for parton scattering, supporting their interpretation in terms of jet production. We find that the jet-event rate represents a sizeable fraction of the inelastic rate and is increasing with √s over the measured energy range.
Search for decays of the W<sup>±</sup> and Z bosons into quark-antiquark pairs
1987, Physics Letters B
The invariant mass distribution of jet pairs observed in the UA2 central calorimeter is examined in the search for an excess of events in the region of the W^± and Z bosons, which would reveal their decays into quark-antiquark pairs. We give a detailed account of the methods of analysis used to optimize the mass resolution achieving ≅±10%. A structure is observed at the level of ≅ 3 standard deviations in the mass region of W^± and Z with shape and position consistent with expectation from their qq̄decays. It contains 632 ± 190 events, 1.4 standard deviations above the standard model prediction of 340 ± 80 events.

Invariant cross section at √s = 28 GeV for coplanar high P<inf>T</inf> clusters selected by a hardware trigger
1987, Nuclear Physics, Section B
In a 400 GeV/c fixed target experiment using a set of geometrical calorimeter triggers we have determined a cross section for pp collisions producing two high P_T coplanar clusters. This cross section was determined without using jet-finding algorithms or appealing to QCD Monte Carlo calculations. Corrections to the data were made by studying hardware triggers designed for that purpose or using experimental data from e⁺e⁻ colliders. The magnitude of the experimental cross section and the P_T slope both agree reasonably well with theoretical QCD predictions for parton-parton scattering that combine non-scaling behavior with fits to recent data from ep, μp, and vp experiments.
