The Quasi-Infra-Red Fixed Point at Higher Loops
arXiv:hep-ph/9610296 · doi:10.1016/S0370-2693(96)01549-3
Abstract
We calculate the four-loop -function for the generalised Wess-Zumino model. We use the result and Padé-Borel summation to discuss the domain of attraction of the quasi-infra-red fixed point of the top-quark Yukawa coupling in the supersymmetric standard model, and argue that the domain is in fact substantial.
