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 …

We outline in detail the properties of generalized parton distributions (GPDs), which contain
new information on the structure of hadrons and which enter the description of hard …

We compute the cross section for leptoproduction of the real photon off the nucleon, which is
sensitive to the deeply virtual Compton scattering amplitude with power accuracy. Our …

We study generalized parton distributions in the impact parameter representation, including
the case of nonzero skewness ξ. Using Lorentz invariance, and expressing parton …

The Lagrangian of Quantum Chromodynamics is invariant under conformal transformations.
Although this symmetry is broken by quantum corrections, it has important consequences for …

Building upon our recent study [GS Bali et al., Eur. Phys. J. C 78, 217 (2018)], we investigate
the feasibility of calculating the pion distribution amplitude from suitably chosen Euclidean …

Perturbative expansions for short-distance quantities in QCD are factorially divergent and
this deficiency can be turned into a useful tool to investigate nonperturbative corrections. In …

Attempting to understand the origin of the intrinsic spin of the proton and neutron has been
an active area of both experimental and theoretical research for the past twenty years. With …

We give a partonic interpretation for the deeply virtual Compton scattering (DVCS)
measurements of the H1 and ZEUS Collaborations in the small-xB region in terms of …
