Constraints on supersymmetric grand unification from<i>b</i>→<i>s</i>γ decay
The top-quark Yukawa infrared fixed-point solution of the renormalization group equations, with minimal supersymmetry and grand unification, defines a low-energy spectrum of supersymmetric particle masses in terms of a few GUT-scale parameters assuming universal boundary conditions. We give predictions in this model for the inclusive b\ensuremath{\rightarrow}s\ensuremath{\gamma} branching fraction and investigate …
