Query: Scaling Law for a Magnetic Impurity Model with Two-Body Hybridization   We consider a magnetic impurity coupled to the hybridizing and screening
channels of a conduction band. The model is solved in the framework of poor
man's scaling and Cardy's generalized theories. We point out that it is
important to include a two-body hybridization if the scaling theory is to be
valid for the band width larger than $U$. We map out the boundary of the
Fermi-non-Fermi liquid phase transition as a function of the model parameters.
