Abstract

A measurement of the direct production of photons with high transverse momentum from\(\bar pp\) collisions at\(\sqrt s = 630\) GeV is presented. The structure of events containing a high transverse momentum photon is studied. The results support predictions from QCD theory.

Abstract

The production of electrons with very high transverse momentum has been studied in the UA2 experiment at the CERN {Mathematical expression} collider ( {Mathematical expression}=540 GeV). From a sample of events containing an electron candidate with pT>15 GeV/c, we extract a clear signal resulting from the production of the charged intermediate vector boson W±, which subsequently decays into an electron and a neutrino. We study the W production and decay properties. Further-more, we refine our results on the production and decay of the neutral vector boson Z0. Finally, we compare the experimental results to the predictions of the standard model of the unified electro-weak theory. © 1984 Springer-Verlag.

Abstract

A study ofW± andZ0 properties has been performed using the UA2 detector at the\(\bar pp\) collider. The data correspond to a total integrated luminosity of 142 nb−1 at\(\sqrt s \)=546 GeV, and of 310 nb−1 at\(\sqrt s \)=630 GeV. The experimental results are compared with the predictions of the Standard Model of the unified electroweak theory.

Abstract

The UA2 experiment, running at the CERN SPS\(\bar pp\) Collider, has performed a study of events containing three hard jets in the final state. The angular distributions of the three jets show evidence for gluon bremsstrahlung, in good agreement with a QCD model to leading order in the strong coupling constant αs. The yield of three-jet events relative to that of two-jet events provides a measure of the strong coupling constant: ;3K3/K2=0.23±0.01±0.04, whereK2 andK3 represent the contributions arising from higher order corrections in α3 to the two- and three-jet exclusive cross-sections. A detailed discussion of the systematic and theoretical uncertainties is given.
