Equivalence of Many-Photon Green Functions in DKP and KGF Statistical Quantum Field Theories
arXiv:hep-th/0309078
Abstract
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 formalism for partition functional in statistical quantum (finite temperature) field theory. We also calculate the polarization operators in these theories in one-loop approximation, and demonstrate their coincidence.
