Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

The strong force which binds hadrons is described by the theory of quantum
chromodynamics (QCD). Determining the character and manifestations of QCD is one of the …

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 …

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 the description of the lowest-energy nucleon excitation—the Δ (1232)-resonance.
Much of the recent experimental effort has been focused on the precision measurements of …

We discuss the links between generalized parton distributions (GPDs) and elastic nucleon
form factors. These links, in the form of sum rules, represent powerful constraints on …

We determine the nucleon electromagnetic form factors and their uncertainties from world
electron scattering data. The analysis incorporates two-photon exchange corrections …

We produce the light-front wave functions (LFWFs) of the nucleon from a basis light-front
approach in the leading Fock-sector representation. We solve for the mass eigenstates from …

Constraints from analyticity are combined with experimental electron-proton scattering data
to determine the proton charge radius. In contrast to previous determinations, we provide a …
