Unification of gauge coupling constants in the minimal supersymmtric model with ${\alpha }_s\approx 0.11$

Abstract

We have studied the gauge unification with the recent electroweak data as a function of the higgsino mass. It was shown that if the strong coupling constant is small $\approx 0.11$, consistent picture of gauge unification is not possible in the minimal supersymmetric standard model.
