Possible pre-LEP200 SUSY threshold signals

If $R$-parity is not conserved, the SUSY-threshold production process $e^+e^- \to \chi_1^0\chi_1^0$ could be detectable with relatively low luminosity. Hence an interesting mass range for the lightest SUSY particle $\chi_1^0$ could be explored at the CERN LEP collider during its intermediate energy development, even before the full LEP200 upgrade is completed. We present cross section formulas and discuss event rates and detection for the three distinct decay options: $\chi_1^0\to 2\, {\rm charged \; leptons}\, +\, {\rm neutrino}$, $\chi_1^0\to {\rm lepton}\, +2\, {\rm quarks}$, and $\chi_1^0\to 3\, {\rm quarks}$.
