A study of high transverse momentum electrons produced in collisions at 540 GeV
msra(1984)
摘要
The production of electrons with very high transverse momentum has been studied in the UA2 experiment at the CERN
collider (
=540 GeV). From a sample of events containing an electron candidate withpT>15 GeV/c, we extract a clear signal resulting from the production of the charged intermediate vector bosonW±, which subsequently decays into an electron and a neutrino. We study theW production and decay properties. Further-more, we refine our results on the production and decay of the neutral vector bosonZ0. Finally, we compare the experimental results to the predictions of the standard model of the unified electro-weak theory.
