This report describes the physics case, the resulting detector requirements, and the evolving
detector concepts for the experimental program at the Electron-Ion Collider (EIC). The EIC …

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” …

Since the parton model was introduced by Feynman more than 50 years ago, much has
been learned about the partonic structure of the proton through a large body of high-energy …

The complicated structure of the neutron cannot be calculated using first-principles
calculations due to the large colour charge of quarks and the self-interaction of gluons. Its …

Proton, as a charge carrier, is most attractive due to its size and the associated advantages.
Recently, reversible proton insertion in electrodes has emerged in electrochemical energy …

The extremely precise extraction of the proton radius obtained by Pohl et al. from the
measured energy difference between the 2 P and 2 S states of muonic hydrogen disagrees …

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 …

Vortex-carrying matter waves, such as chiral electron beams, are of significant interest in
both applied and fundamental science. Continuous-wave electron vortex beams are …

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