HERA, the first electron-proton collider, has been delivering luminosity since 1992. It is the
natural extension of an impressive series of fixed-target lepton-nucleon scattering …

▪ Abstract We present an overview of the scientific opportunities that would be offered by a
high-energy electron-ion collider. We discuss the relevant physics of polarized and …

Due to the momentum transfer r≡ p− p′ from the initial proton to the final, the “asymmetric”
matrix element〈 p′| G… G| p〉 that appears in the pQCD description of hard diffractive …

This report is based on a ten-week program on" Gluons and the quark sea at high-energies",
which took place at the Institute for Nuclear Theory in Seattle in Fall 2010. The principal aim …

We outline the physics opportunities provided by the Electron Ion Collider (EIC). These
include the study of the parton structure of the nucleon and nuclei, the onset of gluon …

We analyze electroproduction of light vector mesons (V=ρ,ϕ) at small Bjorken-x in an
approach that includes the gluonic generalized parton distributions and a partonic …

We develop the novel description of diffractive deep inelastic scattering based on the
technique of lightcone wave functions of multiparton Fock states of the photon. The …

We develop the color dipole phenomenology of diffractive photo-and electroproduction γ*
N→ V (V′) N of light vector mesons (V (1 S)= ϕ 0, ω 0, ρ 0) and their radial excitations …

Diffractive electroproduction of ρ and ϕ mesons is measured at HERA with the H1 detector
in the elastic and proton dissociative channels. The data correspond to an integrated …

Hard diffractive electroproduction of longitudinally polarized vector mesons is calculated
within the leading α s ln (Q 2 Λ QCD 2) approximation of QCD using the leading order parton …
