Studies of the structure of excited baryons are key to the N* program atJefferson Lab. Within the first year of data taking with the Hall B CLAS12detector following the 12 GeV upgrade, a dedicated experiment will aim toextract the N* electrocouplings at high photon virtualities Q2. This experimentwill allow exploration of the structure of N* resonances at the highest photonvirtualities ever yet achieved, with a kinematic reach up to Q2 = 12 GeV2. Thishigh-Q2 reach will make it possible to probe the excited nucleon structures atdistance scales ranging from where effective degrees of freedom, such asconstituent quarks, are dominant through the transition to where nearlymassless bare-quark degrees of freedom are relevant. In this document, wepresent a detailed description of the physics that can be addressed through N*structure studies in exclusive meson electroproduction. The discussion includesrecent advances in reaction theory for extracting N* electrocouplings frommeson electroproduction off protons, along with QCD-based approaches to thetheoretical interpretation of these fundamental quantities. This program willafford access to the dynamics of the non-perturbative strong interactionresponsible for resonance formation, and will be crucial in understanding thenature of confinement and dynamical chiral symmetry breaking in baryons, andhow excited nucleons emerge from QCD.
