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” …

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 …

In recent years, machine learning has emerged as a powerful computational tool and novel
problem-solving perspective for physics, offering new avenues for studying strongly …

Abstract This White Paper aims at highlighting the important benefits in the science reach of
the EIC. High luminosity operation is generally desirable, as it enables producing and …

Tools necessary for quantum simulations of 1+ 1 dimensional quantum chromodynamics are
developed. When formulated in axial gauge and with two flavors of quarks, this system …

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 …

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 …

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

The Fortran LHAPDF library has been a long-term workhorse in particle physics, providing
standardised access to parton density functions for experimental and phenomenological …

A bstract We present NNPDF3. 0, the first set of parton distribution functions (PDFs)
determined with a methodology validated by a closure test. NNPDF3. 0 uses a global …
