THE EFFECTIVE EXPERIMENTAL CONSTRAINTS ON MU-SUSY AND MU-GUT

A comprehensive analysis of the world-data on alpha(s) is reported together with its average value at the Z0 mass. The effective constraints on M(SUSY) and M(GUT) are given. The care needed to reach any conclusion on M(SUSY) is discussed. For example, taking for the alpha-1, alpha-2, alpha-3 coupled equations a numerical solution (it should be the most reliable one) and the two standard deviation limits in the uncertainty of the alpha(s)(M(Z0)) world average, the expected M(SUSY) values range from 10(0.5 +/- 0.5) GeV to 10(5 +/- 1) GeV, from GeV to PeV.
