Results from the N* program at JLab

Understand

We discuss the results on the fundamental degrees of freedom underlying the nucleon excitation spectrum and how they evolve as the resonance transitions are investigated with increasingly better space-time resolution of the electromagnetic probe.

• The search for undiscovered but predicted states continues to be pursued with a vigorous experimental program.
• While recent data from JLab and elsewhere provide intriguing hints of new states, final conclusions will have to wait for the results of the broad experimental effort currently underway with CLAS, and subsequent analyses involving the EBAC at JLab.
