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 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 …

The Fourier transform of generalized parton distribution functions at ξ= 0 describes the
distribution of partons in the transverse plane. The physical significance of these impact …

We develop the concept of quantum phase-space (Wigner) distributions for quarks and
gluons in the proton. To appreciate their physical content, we analyze the contraints from …

Generalized parton distributions (GPDs) with a purely transverse momentum transfer can be
interpreted as Fourier transforms of the distribution of partons in impact parameter space …

While the form factors and parton distributions provide separately the shape of the proton in
coordinate and momentum spaces, a more powerful imaging of the proton structure can be …

▪ Abstract This review explains why generalized parton distributions and the related
quantum phase-space distributions are useful in exploring the quark and gluon structure of …

The present experiment exploits the interference between the deeply virtual Compton
scattering (DVCS) and the Bethe-Heitler processes to extract the imaginary part of DVCS …

Azimuthal asymmetries in exclusive electroproduction of real photons are measured for the
first time with respect to transverse target polarisation, providing new constraints on …
