Abstract

An overview is given of the exploration of baryon properties in meson photo- and electroproduction at Jefferson Lab. These processes provide ample information relevant to the study of electromagnetic couplings of baryon resonances and to the search for states, yet to be discovered. The CLAS detector, combined with the use of energy-tagged polarized photons and polarized electrons, as well as polarized targets, and the measurement of recoil polarization, provide the tool for a comprehensive nucleon resonance program. The status of this program, prospects for the coming years and plans for the Jefferson Lab 12 GeV upgrade are described.

Keywords
