Journal ArticleDOI
TL;DR: In this paper, localized energy clusters (jets) with transverse energy between 5 and 13 GeV are observed semi-inclusively in proton-antiproton interactions with √s = 630GeV which also contain a final state proton with more than 90% of the beam proton's momentum.

Journal ArticleDOI
TL;DR: The UA2 experiment at the CERN p p Collider has identified a total sample of 251 W→eν events as mentioned in this paper, of which 221 were without jets and 29 with one jet.

Journal ArticleDOI
TL;DR: In this paper, a measurement of the direct production of photons with high transverse momentum from collisions at δ(n ϵ s = 630 ϵ GeV ) was presented.
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.

Journal ArticleDOI
TL;DR: In this article, the construction and performance of a 1 m2 silicon hodoscope detector for the upgraded UA2 apparatus is described, and the motivation to construct a second array of smaller dimensions is also presented.
