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 …

The last decade has seen a marked shift in how the internal structure of hadrons is
understood. Modern experimental facilities, new theoretical techniques for the continuum …

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 provide a concise overview on transverse momentum dependent (TMD) parton
distribution functions, their application to topical issues in high-energy physics …

A bstract We present an extraction of unpolarized partonic transverse momentum
distributions (TMDs) from a simultaneous fit of available data measured in semi-inclusive …

The general question, crucial to an understanding of the internal structure of the nucleon, of
how to split the total angular momentum of a photon or gluon into spin and orbital …

This handbook provides a comprehensive review of transverse-momentum-dependent
parton distribution functions and fragmentation functions, commonly referred to as …

The last five years have brought considerable progress in the study of the bound-state
problem in continuum quantum field theory. We highlight a subset of that progress; viz., that …

A bstract We perform a global fit of the available polarized Semi-Inclusive Deep Inelastic
Scattering (SIDIS), polarized pion-induced Drell-Yan (DY) and W±/Z boson production data …

We study the Wigner functions of the nucleon which provide multidimensional images of the
quark distributions in phase space. These functions can be obtained through a Fourier …
