Exclusive vector meson production and small-x evolution

Understand

The process of exclusive elastic vector meson production in deep inelastic scattering is investigated within the dipole model framework supplemented by the small $x$ evolution.

• The dipole-proton amplitude is obtained from the nonlinear Balitsky-Kovchegov evolution equation with impact parameter dependence.
• This dipole amplitude is used to compute the differential cross section for exclusive production of J/\Psi, \phi, and \rho, vector mesons.
• These numerical calculations are compared with the wide range of experimental data from HERA.
