A generalization of the standard spin-boson model is considered. The Hamiltonian H(:) of the model with a coupling parameter : # R acts in the tensor product H F b of a Hilbert space H and the boson (symmetric) Fock space F b over L 2 (R & ). The existence and uniqueness of ground states of H(:) are
