摘要：

We present a numerical study of the complete parameter space of the minimal supersymmetric unified model when the seed of supersymmetry breaking is a universal gaugino mass (m1/2), as is the case in typical no-scale supergravity models. After imposing all consistency and experimental constraints on the model, we obtain a rather restricted range of the allowed values of m1/2: 100 less-than-or-similar-to m1/2 less-than-or-similar-to 300 (400) GeV for mu > 0 (mu < 0). This scenario predicts all supersymmetric particle masses to be below 1 TeV, with all the sleptons below 290 GeV. In fact, the choice of just three parameters, namely m(t), tan-beta, and m1/2, completely determines all masses and couplings in the model, and hence makes it a highly predictive and testable scenario.
