Abstract
The p-meson electromagnetic form factors are calculated, both in covar iant and light-front frameworks with constituent quarks. The effect of the breakdown of rotational symmetry for the one-body current operato r in the null plane is investigated by comparing calculations within l ight-front and covariant approaches. This allows to choose the appropr iate light-front prescription, among the several ones, to best evaluat e the p-meson form factors.
