Relativistic particle dynamics in D=2+1
J. S. Valverde, M. Pazetti
We propose a SUSY variant of the action for a massless spinning particles via the inclusion of twistor variables. The action is constructed to be invariant under SUSY transformatio…
Electromagnetic field at Finite Temperature: A first order approach
R. Casana, B. M. Pimentel, J. S. Valverde
In this work we study the electromagnetic field at Finite Temperature via the massless DKP formalism. The constraint analysis is performed and the partition function for the theory…
Pseudoclassical Mechanics for the spin 0 and 1 particles
R. Casana, M Pazetti, B. M. Pimentel +1
We give an action for the massless spinning particle in pseudoclassical mechanics by using grassmann variables. The constructed action is invariant under -reparametrizations, lo…
Bose-Einstein Condensation and Free DKP field
R. Casana, V. Ya. Fainberg, B. M. Pimentel +1
The thermodynamical partition function of the Duffin-Kemmer-Petiau theory is evaluated using the imaginary-time formalism of quantum field theory at finite temperature and path int…
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…
Duffin-Kemmer-Petiau Theory in the Causal Approach
J. T. Lunardi, L. A. Manzoni, B. M. Pimentel +1
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…
