The interplay of soft and hard contributions in the electromagnetic pion form factor

High Energy Physics - Phenomenology 2009-11-07 v1

Abstract

We consider various relativistic models for the valence Fock-state wave function of the pion. These models are obtained from simple instant-form wave functions by applying a Melosh rotation to the spin part and by imposing physical constraints on the parameters. We discuss how the soft and the hard (perturbative) parts of the electromagnetic form factor are affected by the choice of the model and by the Melosh rotation.
