Precision Data Parameters and Grand Unification Predictions
Nir Polonsky
Abstract
When realizing the Minimal Supersymmetric Standard Model (MSSM) within a (simple) Grand Unified Theory (GUT), the predicted ranges for the strong coupling and the ratio of two Higgs doublet expectation values are strongly correlated with the weak angle and the t-quark mass. (The latter are extracted from precision data.) We spell out those relations and point out the implication for the mass of the light MSSM (CP even) Higgs boson.
