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 outline the many physics opportunities offered by a multi-purpose fixed-target
experiment using the proton and lead–ion beams of the LHC extracted by a bent crystal. In a …

This biennial Review summarizes much of particle physics. Using data from previous
editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average …

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 …

All the leading-twist parton distribution functions are calculated in a spectator model of the
nucleon, using scalar and axial-vector diquarks. Single gluon rescattering is used to …

The role of intrinsic k⊥ in inclusive and semi-inclusive Deep Inelastic Scattering processes
(ℓ p→ ℓ h X) is studied with exact kinematics within QCD parton model at leading order; the …

We discuss in detail a method to study transverse momentum dependent parton distribution
functions (TMDs) using lattice QCD. To develop the formalism and to obtain first numerical …

The state of the art concerning transverse-spin and transverse-momentum phenomena in
hard hadronic reactions is reviewed. An account is given of single-spin and azimuthal …

The differential cross section of exclusive diffractive vector meson production in electron
proton collisions carries important information on the geometric structure of the proton. More …

The most recent data on the weighted transverse single spin asymmetry AUT sin⁡(ϕ h-ϕ S)
from HERMES and COMPASS Collaborations are analyzed within the LO parton model with …
