TL;DR: In this article, a study of W± and Z0 properties has been performed using the UA2 detector at the Ω(bar pp) collider, and the experimental results are compared with the predictions of the Standard Model of the unified electroweak theory.
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.

TL;DR: In this paper, the UA2 experiment at the CERN SPS\(\bar pp\) Collider has performed a study of events containing three hard jets in the final state, and 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.
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.

TL;DR: In this paper, a method based on well-known optical techniques was proposed to measure the free-fall accelaration of bodies of different nuclear compositions, and the sensitivity of the method was almost a factor of 10 higher than in the experiment of Eotvos et al.
