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…
Covariant and ligth-front approaches to the rho-meson eletromagnetic form factors
J. P. B. C de Melo, T. Frederico
The rho-meson eletromagnetic form factors are calculated, both in covariant and light-front framework with constituintes quarks. The effect of the breakdown rotational symmetry for…
