A model of quantum scalar dypole-type field

We examine an arbitrary dimensional 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 finite temperature scalar (Higgs)-Yukawa model at a fixed value of the scalar self-coupling Λ is investigated. The derivative relation of the physical neutral scalar field mass with respect to nonzero temperature is illustrated. 10 refs
