Covariant and light front approaches to the rho meson electromagnetic form-factors

The {rho}-meson electromagnetic form factors are calculated, both in covariant and light-front frameworks with constituent quarks. The effect of the breakdown of rotational symmetry for the one-body current operator in the null plane is investigated by comparing calculations within light-front and covariant approaches. This allows to choose the appropriate light-front prescription, among the several ones, to best evaluate the {rho}-meson form factors. {copyright} {ital 1997} {ital The American Physical Society}
