Covariant and Light-front Approaches to the Ρ-meson Electromagnetic Form-factors *


The ρ-meson electromagnetic form-factors are calculated, both in a covari-ant 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… (More)
