A Study of High Transverse Momentum Electrons Produced in pp Collisions at 540 GeV

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

Measurement of W± and Z0 properties at the CERN {Mathematical expression}p collider

A study of W± and Z0 properties has been performed using the UA2 detector at the {Mathematical expression} collider. The data correspond to a total integrated luminosity of 142 nb-1 at {Mathematical expression}=546 GeV, and of 310 nb-1 at {Mathematical expression}=630 GeV. The experimental results are compared with the predictions of the Standard Model of the unified electroweak theory. © 1986 Springer-Verlag
