Duffin-Kemmer-Petiau theory in the causal approach
Lunardi, José Tadeu Teles; Manzoni, Luiz Alberto; Escobar, Bruto Max Pimentel; Salvador, Juan Segundo Valverde (2002)In this paper we consider the scalar sector of Duffin-Kemmer-Petiau theory in the framework of Epstein-Glaser causal method. We calculate the lowest order distributions for Compton scattering, vacuum polarization, self-energy ... -
Remarks on the duffin-kemmer-petiau theory and gauge invariance
Lunardi, José Tadeu Teles; Escobar, Bruto Max Pimentel; Teixeira, Randall Guedes; Salvador, Juan Segundo Valverde (2000)Two problems relative to the electromagnetic coupling of Duffin-Kemmer-Petiau (DKP) theory are discussed: the presence of an anomalous term in the Hamiltonian form of the theory and the apparent difference between the ...
