We report the 2018 self-consistent values of constants and conversion factors of physics and
chemistry recommended by the Committee on Data of the International Science Council …

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 …

Abstract This White Paper presents an overview of the current status and future perspective
of QCD research, based on the community inputs and scientific conclusions from the 2022 …

This paper gives the 1998 self-consistent set of values of the basic constants and conversion
factors of physics and chemistry recommended by the Committee on Data for Science and …

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 …

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 …

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 …

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