Jets-plus-missing-momentum events in electron-positron annihilation at theZ0peak

In the framework of supersymmetry, cross sections for $e^{\mathrm{-}}$ $e^{+}$→$Z^0$→jets+missing transverse momentum with proper acceptance cuts are determined; both the heavy-gluino and light-gluino ‘‘scenarios’’ are considered. Characteristic features of these cross sections are discussed. If scalar quarks with mass ≲70 GeV exist, it is found that a substantial number of events can be detected at CERN LEP I or the Stanford Linear Collider; this particularly holds for a light gluino.
