Renormalization of generalized scalar Duffin-Kemmer-Petiau electrodynamics

Abstract: The main goal of this work is to study systematically the quantum aspects of the interaction between scalar particles in the framework of Generalized Scalar Duffin-Kemmer-Petiau Electrodynamics (GSDKP). For this purpose the theory is quantized after a constraint analysis following Dirac's methodology by determining the Hamiltonian transition amplitude. In particular, the covariant transition amplitude is established in the generalized non-mixing Lorenz gauge. The complete Green's functions are obtained through… Show more

“…In BFV formalism the method of Faddeev-Popov-DeWitte is elucidated and questions about attainability of gauges are discussed clearly. This work complements previous studies of the authors on covariant quantum dynamics [37,46] and opens the door to a more complete approach, involving the Matsubara-Fradkin formalism of quantum covariant dynamics in equilibrium [47].…”

“…This raises the question of what is role of this algebra in the study of the quantum interaction between the DKP fields (mesons) and Podolsky fields (generalized photons). The next step would be formulate the renormalization program and it is possible to study GSDKP at thermodynamical equilibrium with the Matsubara-Fradkin formalism [5,6].…”

“…With the functional generator of GSDKP besides studying the Dyson-Schwinger covariant quantum equations and Ward-Takahashi identities from quantum gauge symmetry, we could establish the multiplicative renormalization procedure in the mass shell. An explicit calculation of the first radiative corrections (1-loop) associated with the photon propagator, meson propagator, vertex, photon-photon four point function utilizing the dimensional regularization method, where the gauge symmetry is manifest, will show two ways of evaluating the renormalization conditions for the pole and residue, due to DKP trilinear algebra, and we will also see that the DKP algebra ensures the functioning of the Ward-Takahashi (WT) identities in the first radiative corrections of the vertex and photon-photon four point function prohibiting UV divergences [47].…”
