LIGHT GLUINO CONTRIBUTION IN HADRONIC DECAYS OF THE Z-BOSON AND TAU-LEPTON TO O(ALPHA(3)(S))

The results of calculation of light gluino contributions to hadronic d ecay widths of the Z boson and tau lepton to O(alpha(s)(3)) are presen ted. The net effect in the case of Z decay is noticeable. For the tau width the effect is very large and, if a light gluino exists, suggests that alpha(s) increases by more than 15% relative to the standard mod el analysis.
