Description

One of the major challenges of modern theoretical and experimental hadron physics is to probe the Q^2 evolution of the transition form factors of a nucleon to its excited states in terms of the underlying fundamental degrees of freedom, namely, quarks and gluons. The pattern of their mass generation is firmly encoded in the non-perturbative solutions of the fundamental equations of motions of continuum QCD. A promising and systematically improvable theoretical effort along with the CLAS, CLAS12 and after potential increase of CEBAF energy up to 22 GeV will allow us to clearly and unequivocally understand and connect the long and short-range dynamics of QCD through charting out the evolution of these transition form factors with the probing photon momentum squared in electro-excitation processes. I will review the progress in this direction within joint effort between continuum QCD and experimental studies of the nucleon resonance electro-excitation amplitudes within the full range of distances where the transition from strongly coupled to perturbative QCD is expected.
