Abstract
In the MSSM the quasi-infrared fixed point for the top-quark Yukawa coupling gives rise to specific predictions for the soft-breaking parameters. We discuss the extent to which these predictions are modified by the introduction of additional “nonholomorphic” soft-breaking terms. We also show that in a specific class of theories, there exists an RG-invariant trajectory for the “nonholomorphic” terms, which can be understood using a holomorphic spurion term.
