Part of the Few-Body Systems book series (FEWBODY, volume 9)


The elastic and transition electromagnetic form factors of mesons are investigated within a light-front constituent quark model. The general formulae for the space-like matrix elements of the one-body component of the electromagnetic current, including both Dirac and Pauli form factors of the constituent quarks, are presented. Our results for the pion charge form factor and the πρ transition form factor are reported and compared with those obtained within various relativistic approaches in a range of values of the fourmomentum transfer accessible to CEBAF.
