A Note on the IR Finiteness of Fermion Loop Diagrams

Abstract

We show that the most general fermion loop diagram is finite in both soft and collinear regions and therefore, it's IR finite. We use this result to express the IR singular structure of a box scalar integral in terms of the IR singular structure of reduced triangle scalar integrals.
