Electroproduction of heavy quarkonia: significance of dipole orientation

no code implementations11 Feb 2021 B. Z. Kopeliovich, M. Krelina, J. Nemchik

The differential cross section $d\sigma/dq^2$ of diffractive electroproduction of heavy quarkonia on protons is a sensitive study tool for the interaction dynamics within the dipole representation.

Probing the Pomeron spin structure with Coulomb-nuclear interference

no code implementations2 Feb 2021 B. Z. Kopeliovich, M. Krelina, I. K. Potashnikova

Electromagnetic effects in elastic amplitude can be equivalently treated either as Coulomb corrections to the hadronic amplitude (Coulomb phase), or as absorption corrections to the Coulomb scattering amplitude.

Heavy quarkonium production in ultraperipheral nuclear collisions

no code implementations12 Aug 2020 B. Z. Kopeliovich, M. Krelina, J. Nemchik, I. K. Potashnikova

We rely on several selected $Q\bar Q$ potentials, which provide the best description of quarkonium spectra and decay widths, as well as data on diffractive electroproduction of quarkonia on protons.
