Renormalization of an effective model Hamiltonian by a counter term
An ill-defined integral equation for modeling the mass-spectrum of mesons is
regulated with an additional but unphysical parameter. This parameter
dependance is removed by renormalization. Illustrative graphical examples are
given.Comment: 3 pages, 3 figures, 1 reference. to be published in Nucl. Phys. B
