Sd. Joglekar et G. Saini, AN INTERPRETATION OF RENORMALIZATION PRESCRIPTION AMBIGUITIES IN PATH-INTEGRAL FORMULATION, Zeitschrift fur Physik. C, Particles and fields, 59(3), 1993, pp. 489-493
We discuss the renormalization of bilinear composite operators in a Fu
jikawa path integral framework at one loop level in the setting of a Y
ukawa-type theory. We show that all ambiguities in their renormalizati
on can be understood within the context of path integral approach as a
rising from the arbitrariness in the choice of basis for the definitio
n of path integral. We conjecture that the renormalization ambiguities
may have a deeper origin and significance than one normally associate
d with.
