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 …

1 Executive summary The purpose of this document is to outline the developing scientific
case for pursuing an energy upgrade to 22 GeV of the Continuous Electron Beam …

The questions of how the bulk of the Universe's visible mass emerges and how it is manifest
in the existence and properties of hadrons are profound, and probe the heart of strongly …

The cosmic ray interaction event generator Sibyll is widely used in extensive air shower
simulations. We describe in detail the properties of Sibyll 2.1 and the differences with the …

We perform the first global QCD analysis of parton distribution functions (PDFs) in the pion,
combining π A Drell-Yan data with leading neutron electroproduction from HERA within a …

We perform the first global QCD analysis of pion valence, sea quark, and gluon distributions
within a Bayesian Monte Carlo framework with threshold resummation on Drell-Yan cross …

We extract the pion valence quark distribution qv π (x) from lattice QCD (LQCD) calculated
matrix elements of spacelike correlations of one vector and one axial vector current …

An electron ion collider has been proposed in China (EicC). It is anticipated that the facility
would provide polarised electrons, protons and ion beams, in collisions with large centre-of …

We investigate the parton distribution functions (PDFs) of the pion and the kaon by
combining quantum chromodynamics (QCD) evolution with the basis light front quantization …
