We summarize the ongoing scientific program of the 12 GeV Continuous Electron Beam
Accelerator Facility (CEBAF) and give an outlook into future opportunities. The program …

The last decade has seen a marked shift in how the internal structure of hadrons is
understood. Modern experimental facilities, new theoretical techniques for the continuum …

This article reviews our current understanding of how the internal quark structure of a
nucleon bound in nuclei differs from that of a free nucleon. The interpretation of …

We review the spectrum and electromagnetic properties of baryons described as relativistic
three-quark bound states within QCD. The composite nature of baryons results in a rich …

Precise proton and neutron form factor measurements at Jefferson Lab, using spin
observables, have recently made a significant contribution to the unraveling of the internal …

Dyson–Schwinger equations furnish a Poincaré covariant framework within which to study
hadrons. A particular feature is the existence of a nonperturbative, symmetry preserving …

There has been much activity in the measurement of the elastic electromagnetic proton and
neutron form factors in the last decade, and the quality of the data has been greatly …

We review recent progress in the investigation of the electroexcitation of nucleon
resonances, both in experiment and in theory. We describe current experimental facilities …

Studies of the structure of excited baryons are key factors to the N* program at Jefferson Lab
(JLab). Within the first year of data taking with the Hall B CLAS12 detector following the 12 …

Generalized parton distributions have been introduced in recent years as a suitable
theoretical tool to study the structure of the nucleon. Unifying the concepts of parton …
