Abstract
The constituent quark rho meson electromagnetic form-factors are calculated, with covariant and null-plane approaches with the same model. The null-plane formalism produces the breakdown of the rotational symmetry for the one-body current operador, wich is investigated by comparing the numerical results in both approaches. This allows to choose the appropriate null-plane prescriptio, among the several ones, to evaluate the rho meson form-factors.
