Diffractive Vector Meson Production In A Unified $\kappa$-Factorization Approach

Abstract

In the framework of the $\kappa$-factorization approach and on the basis of recently determined DGSF, we calculated the production rates of ground and excited (2S and D wave) states of vector mesons and investigated their various kinematical and spin dependencies. We also addressed the issue of S/D wave mixing in quarkonia.
