摘要：

The results for the running of gauge couplings in the MSSM are updated by proper inclusion of all low scale effects. They are presented as predictions for the strong coupling constant in the scenario with only two parameters at the GUT scale (alpha(U) and M(U)) and as a mismatch of the couplings at the scales similar to 3 x 10(16) GeV and 4 x 10(17) GeV, when all three couplings are taken as the experimental input.
