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 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 …

The inspiration for this book came from François le Diberder. During his term as
spokesperson for B 八 B 八 R he laid down a vision for the two B Factory detector …

Within the theory of Quantum Chromodynamics (QCD), the rich structure of hadrons can be
quantitatively characterized, among others, using a basis of universal nonperturbative …

This article reviews our present understanding of QCD spin physics: the proton spin puzzle
and new developments aimed at understanding the transverse structure of the nucleon …

The field of fragmentation functions of light quarks and gluons is reviewed. In addition to
integrated fragmentation functions, attention is paid to the dependence of fragmentation …

We study the transverse-momentum-dependent (TMD) evolution of the Collins azimuthal
asymmetries in e+ e-annihilations and semi-inclusive hadron production in deep inelastic …

We present the first direct calculation of the renormalized transversity parton distribution
function within the nucleon from lattice QCD. The calculation is performed using simulations …

We produce the light-front wave functions (LFWFs) of the nucleon from a basis light-front
approach in the leading Fock-sector representation. We solve for the mass eigenstates from …

We present the first extraction of the transversity distribution in the framework of collinear
factorization based on the global analysis of pion-pair production in deep-inelastic scattering …
