Scientific paper

In this talk we discuss the constraints on supersymmetry arising from data from a number of recent experiments. There appears to be good cumulative evidence from experiment in favor of positivity of the sign of the Higgs mixing parameter $\mu$. Implications of this result for Yukawa unification are discussed since Yukawa unification is sensitive to the $\mu$ sign. An analysis of dark matter under the constraints of Yukawa unification is also given. It is shown that the simultaneous imposition of all existing constraints sharply defines the parameter space of models. Specifically models with nonuniversality of gaugino masses provide a simple resolution to the positivity of the $\mu$ parameter and Yukawa unification. Implications of these results for colliders and for the next generation of dark matter searches are also discussed.
