Baryon resonance electromagnetic transition form factors in a light-cone model

Calculations using a constituent quark model of the electromagnetic form factors for transitions between nucleons and excited states of the nucleon with J=1/2 and 3/2, including the Roper resonance, are described. These form factors are calculated with a relativistic model based on light-cone dynamics, fit to the proton and neutron elastic form factors, and using wave functions determined from the solution of a realistic three-quark Hamiltonian.
