Finite Algebraic Quantum Field Theory

Abstract

Based on a recently proposed quantum field theory (QFT) for particles with or without structure, called "Structural Algebraic QFT (SAQFT)", we introduce a finite QFT. That is, a QFT for structureless elementary particles that does not require renormalization where loop integrals in the Feynman diagrams are finite. It is an algebraic theory utilizing orthogonal polynomials and based on the structureless sector of SAQFT.
