The coupling of a scalar-meson field to the trace of the energy-momentum tensor is formulated in terms of a nonpolynomial interaction Lagrangian. Quantization and applications are discussed.

In an attempt to account for the charge distributions of the proton and the neutron as indicated by the electron scattering experiments,' we would like to consider the possibility that there may be a… Expand

mathematical theory of order-disorder transition. The problem of determining the partition function for a lattice with simple interaction model was found, by severai authors,!) to be reduced to an… Expand

Abstract Dispersion relations for nucleon-nucleon scattering are presented. The general case of nonforward scattering is treated, although the majority of the discussion is confined to the limiting… Expand

Relativistic dispersion relations are used to derive equations for low-energy S-, P-, and D-wave meson-nucleon scattering under the assumption that the (3,3) resonance dominates the dispersion… Expand
