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 …

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 …

Among the most fundamental observables of nucleon structure, electromagnetic form factors
are a crucial benchmark for modern calculations describing the strong interaction dynamics …

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

Nucleons (protons and neutrons) are the building blocks of atomic nuclei and are
responsible for more than 99% of the visible matter in the Universe. Despite decades of …

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 …

Background: Interest in the behavior of nucleon electromagnetic form factors at large
momentum transfers has steadily increased since the discovery, using polarization …

We review recent theoretical and experimental progress on the role of two-photon exchange
(TPE) in electron–proton scattering at low to moderate momentum transfers. We make a …
