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 …

We provide an updated recommendation for the usage of sets of parton distribution functions
(PDFs) and the assessment of PDF and PDF+ ${\alpha} _ {s} $ uncertainties suitable for …

We present a new set of parton distributions, NNPDF3. 1, which updates NNPDF3. 0, the first
global set of PDFs determined using a methodology validated by a closure test. The update …

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 …

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 …

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 …

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 …
