Renormalization Group Coefficients for the Un-Truncated Derivative Expansion in Effective Field Theory

Abstract

We investigate the renormalization of ``nonlocal" interactions which arise as an infinite sum of higher derivative interactions in an effective field theory. Using dimensional regularization with minimal subtraction in a general scalar field theory, we write an integro-differential renormalization group equation for the most general graph at one loop order.
