Bogoliubov’s causal perturbative QED and white noise. Interacting fields

We present Bogoliubov’s causal perturbative QFT with a single refinement: the creation–annihilation operators at point, i.e., for specific momentum, are mathematically interpreted as Hida from white noise analysis. leave rest of theory completely unchanged. This allows avoiding infrared and ultraviolet divergences in transition to adiabatic limit interacting fields. existence proof fields QED operators. exists if only normalization Epstein–Glaser splitting distributions, construction scattering operator, is “natural,”, which eliminates arbitrariness choosing that makes definite, its predictive power considerably strengthened. example charge–mass relation can be proved within this confirmed experimentally.
