{wiki=Schwinger_parametrization}
Schwinger parametrization is a technique used in quantum field theory and theoretical physics to rewrite certain types of integrals, particularly those that involve propagators or Green's functions. This method allows for a more amenable form of integration, especially in the context of loop integrals or when evaluating Feynman diagrams.
