Two-point function of nonlinear spinor theory

Abstract

The influence of interaction on the nature of the quantum field is investigated for a self-interacting spinor theory. Nonlinear equations for the two-point function are formulated. The solutions of these equations demonstrate that fields in interaction exhibit novel features. In particular, the modified short-distance behavior indicates the absence of pathological features, implying self-regulation of nonlinear systems with concomitant noncanonical quantization.
