What have we learned recently from few-GeV Electroweak Reactions?
In the past few years, high precision data on electromagnetic reactions of
the nucleon in the few GeV energy region have rapidly been accumulated at
Jefferson Laboratory and several laboratories around the world. Furthermore,
there is a possibility that high quality neutrino scattering data in the same
energy region could be available in the near future at several neutrino
Facilities currently under construction. These developments have provided
tremendous opportunities for understandng the non-perturbative aspects of
hadron structure and interactions.
I will review recent advances in this research area and discuss opportunities
for future developments. The subjects to be covered include: the structure
of nucleon and nucleon resonances; hadron models and Lattice QCD
calculations; reaction mechanisms of few-GeV electroweak meson production
reactions; and the transition to perturbative QCD.
