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 …

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

This report is based on a ten-week program on" Gluons and the quark sea at high-energies",
which took place at the Institute for Nuclear Theory in Seattle in Fall 2010. The principal aim …

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 …

We investigate the transverse-momentum-dependence in semi-inclusive deep inelastic
leptoproduction of hadrons. There are two different theoretical approaches to study this …

We provide an experimental and theoretical perspective on the behavior of unpolarized
distribution functions for the nucleon and pion on the valence-quark domain; namely …

A bstract Recent experimental data on semi-inclusive deep-inelastic scattering from the
Hermes collaboration allow us to discuss for the first time the flavor dependence of …

A bstract The unpolarised transverse momentum dependent distribution and fragmentation
functions are extracted from HERMES and COMPASS experimental measurements of SIDIS …

Extensive experimental and theoretical explorations over the last decades showed that the
nucleon (proton/neutron) is not just a simple system of 3 quarks bound by gluons, but a …

The nucleons (protons and neutrons) are by far the most abundant form of matter in our
visible Universe; they are composite particles made of quarks and gluons, the fundamental …
