Summary
We examine an arbitrary order dimension system of two scalar neutral fields by means of a 1/N expansion method. Using the partial normal-ordering procedure, an application in the study of a light scalar dipole-type field interaction with quarks is proposed. A hypothetical candidate for a (pseudo)-scalar coupling between the quarks inside the bound system would be a light Higgs-like exotic X-particle. The derivative relation of the physical neutral scalar field mass with respect to non-zero temperature is illustrated.
