Recoil Model in Quantum Field Theory

Physical Review, 1962
The static-source model is generalized to allow for the recoils and the mutual degrees of freedom of the source'' particles by adding to the Hamiltonian corresponding to the field and its sources the nonrelativistic Hamiltonian for the motion of the heavier particles. The resulting system can be quantized.

Diffeomorphism cohomology in quantum-field-theory models

Physical Review D, 1988
We show that the cohomology of the Becchi-Rouet-Stora diffeomorphism operator on the integrated functions in ${\mathrm{R}}^{d}$ can be easily computed as a series whose terms contain the cohomology elements of the same operator on the unintegrated functions.

Renormalization of a model quantum field theory

American Journal of Physics, 1992
Renormalization is the technique used to eliminate infinities that arise in quantum field theory. This paper shows how to renormalize a particularly simple model, in which a single mass counterterm of second order in the coupling constant suffices to cancel all divergences.

Scattering theory in a model of quantum fields. I

Journal of Mathematical Physics, 1973
We study a model of quantum field theory with ``Yukawa-like'' interaction λ∫Φb+(x)Φb−(x)Φa(x)d x between nucleons (b) and mesons (a). It is a version of Nelson's model with relativistic kinematics and has been renormalized by J. P. Eckmann. The infinite mass renormalization is a power series in λ2, chosen in such a way as to confer on the renormalized ...
