Lj. Clavelli et Lr. Surguladze, LIGHT GLUINO CONTRIBUTION IN HADRONIC DECAYS OF THE Z-BOSON AND TAU-LEPTON TO O(ALPHA(3)(S)), Physical review letters, 78(9), 1997, pp. 1632-1635
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.
