Abstract The interaction of spatially small dipoles with nucleons, nuclei is calculated in the DGLAP approximation at the top of HERA energies and found to be close to the S -channel unitarity limit in the case of the color octet dipoles. The DGLAP analyses of the current diffractive data appear to support this conclusion as they indicate a ∼ 30 – 40% probability of the gluon induced diffraction for Q 2 ∼ 4 GeV 2 . The need for the high-precision measurements of the t -dependence of inclusive… 
SMALL-x PHYSICS: From HERA to LHC and Beyond
▪ Abstract We summarize the lessons learned from studies of hard scattering processes in high-energy electron-proton collisions at HERA and antiproton-proton collisions at the Tevatron, with the aim
DGLAP versus perturbative Pomeron in large momentum transfer hard diffractive processes at HERA and LHC
Abstract We evaluate within the LO DGLAP approximation the dependence on energy of the cross section of the photo(electro)production of vector meson V ( V = J / ψ , … ) in the hard elastic processes
On the universality of cross sections of hadron–hadron (nuclei) collisions at superhigh energies
Abstract We analyze the interplay of the hard and soft interaction dynamics in the onset of the black body limit in the high energy hadron–hadron and hadron–nucleus collisions. We demonstrate that
The energy dependence of the hard exclusive diffractive processes in pQCD as the function of momentum transfer
We predict the dependence on energy of photo (electro) production processes: γ(γ*)+p→V+X with large rapidity gap at small x and large momentum −t transferred to V in pQCD. Here V is a heavy

QCD Explorer Based ea and gamma-a Colliders

contribution to diffractive J/ψ electroproduction
We study the diffractive electroproduction of quarkonia from quark-antiquark-gluon states in the photon wave function. We show that these states contribute to the leading-power and leading-logarithm
Pomeron structure and diffractive parton distributions
Measurements of the diffractive structure function, F2D, of the proton at HERA are used to extract the partonic structure of the Pomeron. Regge Factorization is tested and is found to describe well
Heavy Quark and Quarkonium Transport in High Energy Nuclear Collisions
Abstract The strong interaction between heavy quarks and the quark gluon plasma makes the open and hidden charm hadrons be sensitive probes of the deconfinement phase transition in high energy
Nuclear Physics at the TESLA*HERA Complex
Construction of the TESLA linear electron-positron collider tangentially to the HERA proton ring will provide a number of new facilities for particle and nuclear physics research. In this paper main


Evidence for enhancement of gluon and valence-quark distributions in nuclei from hard lepton-nucleus processes.
Current data on deep-inelastic processes off nuclei are analyzed by using exact QCD sum rules for the total momentum and baryon charge of nuclei. Evidence for an overall enhancement of the gluon
The Hadronic Properties of the Photon in High-Energy Interactions
High-energy photon interactions are discussed in terms of the hadronic structure of the photon, which is expressed by means of a formulation which is akin to, but somewhat more general than,
Perturbative gluon shadowing in heavy nuclei.
The ratios of the distributions at an initial scale [ital Q][sub 0]=2 GeV are studied, and it is shown that a strong nuclear shadowing can follow from the modified QCD evolution.
Unified description of nuclear shadowing of virtual photons
Abstract The nuclear structure function is analysed in the shadowing region for small and moderately large values of Q 2 . Both the vector meson rescattering and the partonic contribution to
Asymptotic behaviour of the scattering amplitude at high energies
Abstract The asymptotic behaviour of the scattering amplitude is investigated at high energies. It is shown that at high energies the usual diffraction picture of scattering contradicts the unitarity
