Abstract
I summarize a part of the work done with Bamert, Burgess, London and Nardi (hep-ph/9602438) in which we find simplified expressions for the possible one-loop contributions to the parameter from new virtual particles, including supersymmetric ones. Our expressions make it easier to identify which models and choices of parameters are best able to solve the problem.
