Search for neutralino pair production at s**(1/2) = 189-GeV
P. Abreu et al., W. Adam, T. Adye, P. Adzic et autres
A search for pair-production of neutralinos at a LEP centre-of-mass energy of 189 GeV gave no evidence for a signal. This limits the neutralino production cross-section and excludes regions in the parameter space of the Minimal Supersymmetric Standard Model (MSSM).
