Abstract

A search for supersymmetric decays of the Z boson into a pair of scalar electrons or winos (partners of the electron and W boson) has been made with the upgraded UA2 experiment at the CERN pp collider at s = 630 GeV. The analysis of the sample of electron pairs, corresponding to an integrated luminosity of 7.4 pb-1, shows no evidence for such exotic decays. The 90% confidence level lower mass limits obtained exclude selectron masses up to e40 GeV/c2 in the case of a light photino, and wino masses up to 45 GeV/c2 in the case of a light scalar neutrino.

N2 - A search for supersymmetric decays of the Z boson into a pair of scalar electrons or winos (partners of the electron and W boson) has been made with the upgraded UA2 experiment at the CERN pp collider at s = 630 GeV. The analysis of the sample of electron pairs, corresponding to an integrated luminosity of 7.4 pb-1, shows no evidence for such exotic decays. The 90% confidence level lower mass limits obtained exclude selectron masses up to e40 GeV/c2 in the case of a light photino, and wino masses up to 45 GeV/c2 in the case of a light scalar neutrino.
