Since the parton model was introduced by Feynman more than 50 years ago, much has
been learned about the partonic structure of the proton through a large body of high-energy …

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 …

We present a detailed analysis of e+ e−→ π+ π− data up to s= 1 GeV in the framework of
dispersion relations. Starting from a family of ππ P-wave phase shifts, as derived from a …

A bstract In this third paper of a series dedicated to a dispersive treatment of the hadronic
light-by-light (HLbL) tensor, we derive a partial-wave formulation for two-pion intermediate …

Traditionally, lattice QCD computations of generalized parton distributions (GPDs) have
been carried out in a symmetric frame, where the transferred momentum is symmetrically …

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 …

We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

We present an improved calculation of B→ light pseudoscalar form factors from light-cone
sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and …

The approximate symmetries of Quantum ChromoDynamics in the infinite heavy quark (Q=
c, b) mass limit (mQ→∞) and in the chiral limit for the light quarks (mq→ 0, q= u, d, s) can be …
