Pion observables within the covariant formulation of Light-front dynamics

Abstract : Within the covariant formulation of light-front dynamics we determine the two spin components of the pion wave function in a phenomenological constituent quarkmodel. These spin components are further interpreted as a non-relativistic wave function and a purely relativistic component. The latter is determined in the one-gluon exchange approximation. We calculate in this model several observables: the pion decay constant, the electromagnetic form factor and the transition form factor.
