Supersymmetric corrections to Higgs decays and b ---> s gamma for large tan beta
If tan beta is large, supersymmetric QCD corrections can become large, putting naive perturbation theory into doubt. I show how these tan-beta-enhanced corrections can be controlled to all orders in alpha_s tanbeta. The result is shown for the decays H^+ -> t b-bar and b -> s gamma.
