Abstract
We consider the infrared quasi-fixed point solutions of the renormalization group equations for the top-quark Yukawa coupling and soft supersymmetry breaking parameters in the MSSM. The ir quasi-fixed points together with the values of the gauge couplings, the top-quark and Z-boson masses allow one to predict masses of the Higgs bosons, the stop squarks and the lightest chargino as functions of the only free parameter m1/2 or the gluino mass. The mass of the lightest Higgs boson for μ>0 and M SUSY ≈ 1 TeV is found to be mh = (94.3+1.6+0.6±5±0.4) GeV. The case with μ<0 is excluded by experimental data.
