Description

Renormalization effects are analyzed for a class of supersymmetric grand unified theories which contain the standard SU(3)/sub c/ x SU(2)/sub L/ x U(1) model. Predictions for sin2theta-circumflex/sub W/(m/sub W/) and the proton lifetime are obtained as functions of Λ/sub M/S (MS is the modified minimal-subtraction scheme), N/sub H/ (number of relatively light Higgs doublets), and μ (the scale of supersymmetry breaking). For realistic input parameters we find 0.23< or =sin2theta-circumflex/sub W/(m/sub W/)< or =0.26 and 1038> or approx. =tau/sub p/> or approx. =1029 yr. Loop effects that could render the larger predicted values of sin2theta-circumflex/sub W/(m/sub W/) consistent with experiment are described
