Abstract
The results for the running of the gauge couplings in the MSSM are up-dated 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 ~ (αU ~and ~MU) ~and as a mismatch of the couplings at the scales ~ 3 × 1016 GeV ~and ~4×1017 GeV, when all three couplings are taken as the experimental input.
