MSSM phenomenology in the large tan β regime

We discuss aspects of the low energy phenomenology of the MSSM, in the large tan β regime. We explore the regions of the parameter space where the ht and hb Yukawa couplings exhibit a fixed point structure, using previous analytic solutions for these coupling. Expressions for the parameters At and Ab and the renormalised soft mass terms are also derived, making it possible to estimate analytically the sparticle loop — corrections to the bottom mass, which are important in this limit.
