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 …

Lepton scattering is an established ideal tool for studying inner structure of small particles
such as nucleons as well as nuclei. As a future high energy nuclear physics project, an …

This White Paper presents the science case of an Electron-Ion Collider (EIC), focused on the
structure and interactions of gluon-dominated matter, with the intent to articulate it to the …

We give an overview of the theory for generalized parton distributions. Topics covered are
their general properties and physical interpretation, the possibility to explore the three …

The most non-trivial of the established microscopic theories of physics is quantum
chromodynamics, QCD, the theory of the strong interaction. A critical link between theory …

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 generalized parton distributions, introduced nearly a decade ago, have emerged as a
universal tool to describe hadrons in terms of quark and gluonic degrees of freedom. They …

An overwhelming number of theoretical predictions for hadron colliders require parton
distribution functions (PDFs), which are an important ingredient of theory infrastructure for …

We study the cross section for one-particle inclusive deep inelastic scattering off the nucleon
for low transverse momentum of the detected hadron. We decompose the cross section in …
