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 …

Abstract The Forward Physics Facility (FPF) is a proposal to create a cavern with the space
and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

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” …

The theory of the strong force, quantum chromodynamics, describes the proton in terms of
quarks and gluons. The proton is a state of two up quarks and one down quark bound by …

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

Neutrinos are copiously produced at particle colliders, but no collider neutrino has ever
been detected. Colliders produce both neutrinos and anti-neutrinos of all flavors at very high …

In the framework of quantum chromodynamics (QCD), parton distribution functions (PDFs)
quantify how the momentum and spin of a hadron are divided among its quark and gluon …

We review recent progress in the determination of the parton distribution functions (PDFs) of
the proton, with emphasis on the applications for precision phenomenology at the Large …

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 …
