摘要

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 ~ ( $\alpha_{U}$ ~and ~ $M_{U}$ ) ~and as a mismatch of the couplings at the scales ~ $\sim 3 \times 10^{16}$ GeV ~and ~ $4\times10^{17}$ GeV, when all three couplings are taken as the experimental input.
