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” …

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 …

This paper describes a precise measurement of electron scattering off the proton at
momentum transfers of 0.003≲ Q 2≲ 1 GeV 2. The average point-to-point error of the cross …

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 use the world's data on elastic electron-proton scattering and calculations of two-photon
exchange effects to extract corrected values of the proton's electric and magnetic form …

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 …

The proton charge radius has been measured since the 1950s using elastic electron–proton
scattering and ordinary hydrogen atomic spectroscopy. In 2010, a highly precise …

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 …

We review the role of two-photon exchange (TPE) in electron–hadron scattering, focusing in
particular on hadronic frameworks suitable for describing the low and moderate Q2 region …
