QCD Modeling of Hadron Physics

COFFEE_KLATCH  · Invited

Abstract

The quest for an understanding of how non-perurbative QCD explains hadronic physics is particularly difficult in the light quark sector and it draws upon experiment, lattice gauge theory and continuum modeling of QCD dynamics. In this talk I will summarize some valuable insights that have been obtained from recent new developments in continuum QCD-modeling of light quark hadrons. Some discussion of the high $Q^2$ behavior of elastic and transition electromagnetic form factors will be included. New calculations of the pion distribution amplitude and elastic form factor combine to clarify a long standing puzzle about the transition domain where a perturbative elastic scattering mechanism takes over. Other meson distribution amplitudes and parton distribution functions may be discussed.
