Abstract
- The production of electrons with very high transverse momentum has been studied in the UA2 experiment at the CERN <img src="/fulltext-image.asp?format=htmlnonpaginated&src=K5621P2185QK6777_html\10052_2005_Article_BF01576282_TeX2GIFIE2.gif" border="0" alt=" $$\bar pp$$ " /> collider ( <img src="/fulltext-image.asp?format=htmlnonpaginated&src=K5621P2185QK6777_html\10052_2005_Article_BF01576282_TeX2GIFIE3.gif" border="0" alt=" $$\sqrt s$$ " />=540 GeV). From a sample of events containing an electron candidate withp<subscript>T</subscript>>15 GeV/c, we extract a clear signal resulting from the production of the charged intermediate vector bosonW<superscript>±</superscript>, 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 bosonZ<superscript>0</superscript>. Finally, we compare the experimental results to the predictions of the standard model of the unified electro-weak theory.
