A golden age for heavy-quarkonium physics dawned a decade ago, initiated by the
confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of …

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 …

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 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 discuss the physics of large impact parameter interactions at the LHC: ultraperipheral
collisions (UPCs). The dominant processes in UPCs are photon–nucleon (nucleus) …

The ALICE Collaboration at the LHC has measured the J/ψ and ψ′ photoproduction at mid-
rapidity in ultra-peripheral Pb–Pb collisions at\(\sqrt {s_ {\mathrm {NN}}}= 2.76~\mathrm …

We develop a dipole model for DESY HERA deep inelastic scattering data which
incorporates the impact parameter distribution of the proton. The model describes the …

We present a simultaneous analysis, within an impact parameter dependent saturated
dipole model, of exclusive diffractive vector meson (J/ψ, ϕ, and ρ) production, deeply virtual …

The ALICE Collaboration has made the first measurement at the LHC of J/ψ photoproduction
in ultra-peripheral Pb–Pb collisions at sNN= 2.76 TeV. The J/ψ is identified via its dimuon …
