Feynman parametrization is a technique for evaluating loop integrals which arise from Feynman diagrams with one or more loops. However, it is sometimes useful in integration in areas of pure mathematics as well. It was introduced by Julian Schwinger[1] and Richard Feynman[2] in 1949 to perform calculations in quantum electrodynamics.[3][4][a]
