Best Fit to the Gluino Mass
  Assuming that perturbative QCD is the dominant explanation for the narrowness of the vector quarkonia, we perform a $\chi^2$ minimization analysis of their hadronic decays as a function of two parameters, the mass of the gluino and the value of ${\alpha}_3(M_Z)$. A value below 1 GeV for the gluino mass is strongly preferred. Consequences for SUSY breaking scenarios are discussed.
