Quasi-infrared fixed points and renormalization group invariant trajectories for nonholomorphic soft supersymmetry breaking - art. no. 095002

In the MSSM the quasi-infrared fixed point for the top-quark Yukawa couplin g gives rise to specific predictions for the soft-breaking parameters. We d iscuss the extent to which these predictions are modified by the introducti on 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 spu rion term.
