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

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 …

The aim of this report is to give basic notions on electromagnetic hadron form factors (FFs),
as they are understood at the present time, to summarize and analyze the present …

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 …

Precise measurements of the proton electromagnetic form factor ratio R= μ p GE p/GM p
using the polarization transfer method at Jefferson Lab have revolutionized the …

The electromagnetic form factors of the proton and the neutron are computed within lattice
QCD using simulations with quark masses fixed to their physical values. Both connected and …
