Abstract
A scaling limit for the generalized spin-boson (GSB) model is considered. We derive a scaling limit of the Hamiltonian of the GSB model independently of whether or not the quantum scalareld has a mass. Applying it to a model for the eld of the nuclear force with isospin, we obtain an effective potential of the interaction between nucleons. Also, we get some applications to condensed matter physics.
