Pion Eletromagnetic Current in the Ligth-Cone Formalism
J. P. B. C. de Melo, H. W. L. Naus, T. Frederico
The electromagnetic form factor of the pion is calculated in a pseudoscalar field theoretical model which constituent quarks. We extract the form factor using the "+" component of…
Ward-Takahashi Identidy on the Ligth-Front
H. W. L. Naus, J. P. B. C de Melo, T. Frederico
The Ward-Takahashi identity, reflecting local gauge invariance, is perturbatively verified for a boson model in light front field theory. A careful integration over the light front…
Construction of gauge invariant effective nucleonic theories: functional approach
H. W. L. Naus
Starting from relativistic quantum field theories, describing interacting nucleons and pions coupled to the dynamical electromagnetic field, the pion degrees of freedom are elimina…
QCD near the Light Cone
H. W. L. Naus, H. J. Pirner, T. J. Fields +1
Starting from the QCD Lagrangian, we present the QCD Hamiltonian for near light cone coordinates. We study the dynamics of the gluonic zero modes of this Hamiltonian. The strong co…
