Equivalence of Many-Photon Green Functions in DKP and KGF Statistical Quantum Field Theories
V. Ya. Fainberg, B. M. Pimentel, J. S. Valverde
We prove the equivalence of many-photon Green functions in statistical quantum field Duffin-Kemmer-Petiau (DKP) and Klein-Gordon-Fock (KGF) theories using functional path integral…

Field gauge divergences in the light-front
J. H. O. Sales, T. Frederico, B. M. Pimentel
The Bethe-Salpeter equation for ground state of two fermions exchanging a gauge boson presents divergences. We used a prescription that allowed an apropriate prescription of the si…
