  We will present the axioms of Bogoliubov's causal perturbative QFT in which
the creation-annihilation operators are interpreted as Hida operators. We will
shortly present the results that can be achieved in this theory: 1. Removal of
UV and IR infinity in the scattering operator, 2. Existence of the adiabatic
limit for interacting fields in QED, 3. Proof that charged particles have
non-zero mass, 4. Existence of infrared and ultraviolet asymptotics for QED.
