The exclusive processes in electron-proton (ep) interactions are an important tool to investigate the QCD dynamics at high energies as they are in general driven by the gluon content of proton which is strongly subject to parton saturation effects. In this paper we compute the cross sections for the exclusive vector meson production as well as the deeply virtual Compton scattering (DVCS) relying on the color dipole approach and considering the numerical solution of the Balitsky-Kovchegov equation including running coupling corrections. We show that the small-x evolution given by this evolution equation is able to describe the DESY-HERA data and is relevant for the physics of the exclusive observables in future electron-proton colliders and in photoproduction processes to be measured in coherent interactions at the LHC.

“…Here, we follows the analytically simple DGKP approach 22 , which assumes that the dependencies on r and z of the wavefunction are factorised, with a Gaussian dependence on r (For a detailed discussion see Refs. 23,24 ). The main shortcoming of this approach is that it breaks the rotational invariance between transverse and longitudinally polarized vector mesons 18 .…”

The ultraperipheral heavy ion collisions (UPC's) are an important alternative to study the QCD dynamics until the next generation of e + e − /ep/eA colliders become reality. Due to the coherent action of all the protons in the nucleus, the electromagnetic field is very strong and the resulting flux of equivalent photons is large, which allows to study two-photon as well as photonuclear interactions at high energies. In this paper we present a brief review of the vector meson production in UPC's at high energies using the QCD color dipole approach to describe their photonuclear production and the perturbative QCD Pomeron (BFKL dynamics) to describe the double meson production in photonphoton process. Predictions for rates and integrated cross sections are presented for energies of RHIC and LHC.

“…The light-cone wave function of the photon splitting into the dipole can be calculated in QED, but the forward wave function of the vector meson cannot be calculated analytically. The forward wave functions of vector meson almost are modeled as the light-cone wave function of the photon, and the models of the vector mesons include the Gauss-LC [28], the DGKP [34,35], the boosted Gaussian [36,37], and so on. This paper is organized as follows: a brief review of the dipole model and the wave function will be presented in Sect.…”

The coherent cross section of J/ψ, ρ, and φ are computed in the dipole model in the ultraperipheral PbPb collisions. The IP-Sat and IIM model are applied in the calculation of the differential cross section of the dipole scattering off the nucleon, and three kinds of forward vector meson wave functions are used in the overlap. The prediction of J/ψ and ρ is compared with the experimental data of the ALICE collaboration, and the prediction of φ is also given in this paper.
