This report reviews the study of open heavy-flavour and quarkonium production in high-
energy hadronic collisions, as tools to investigate fundamental aspects of Quantum …

Abstract Quark–Gluon Plasma (QGP), a QCD state of matter created in ultra-relativistic
heavy-ion collisions, has remarkable properties including, for example, a low shear viscosity …

I introduce a gauge-invariant decomposition of the nucleon spin into quark helicity, quark
orbital, and gluon contributions. The total quark (and hence the quark orbital) contribution is …

We study in QCD the physics of deeply virtual Compton scattering (DVCS)—the virtual
Compton process in the large s and small t kinematic region. We show that DVCS can probe …

We give an overview of the theory for generalized parton distributions. Topics covered are
their general properties and physical interpretation, the possibility to explore the three …

The most non-trivial of the established microscopic theories of physics is quantum
chromodynamics, QCD, the theory of the strong interaction. A critical link between theory …

Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

The physics programme and the design are described of a new collider for particle and
nuclear physics, the Large Hadron Electron Collider (LHeC), in which a newly built electron …

Applications of perturbative QCD to deeply virtual Compton scattering and hard exclusive
electroproduction processes require a generalization of usual parton distributions for the …

The generalized parton distributions, introduced nearly a decade ago, have emerged as a
universal tool to describe hadrons in terms of quark and gluonic degrees of freedom. They …
