Infrared and ultraviolet power counting on the mass shell in quantum electrodynamics
A power counting rule is provided that allows us to obtain upper bounds for the absolute values of Feynman parametric integrands. The rule reflects both the ultraviolet and infrared behaviour taking into account that the external momenta are on the mass shell. It gives us the ability to rigorously p...
