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 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 …

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” …

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

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 …

A bstract We present an extraction of unpolarized transverse-momentum-dependent parton
distribution and fragmentation functions based on more than two thousand data points from …

We present high-accuracy QCD predictions for the transverse-momentum (q T) distribution
and fiducial cross sections of Drell–Yan lepton pairs produced in hadronic collisions. At …

A bstract We consider semi-inclusive deep inelastic scattering (SIDIS) and Drell-Yan events
within transverse momentum dependent (TMD) factorization. Based on the simultaneous fit …

The strong force which binds hadrons is described by the theory of quantum
chromodynamics (QCD). Determining the character and manifestations of QCD is one of the …
