Pair production of heavy quarkonia in the color evaporation model

Abstract

In the article, we study pair production of heavy quarkonia $(J/\psi J/\psi ,{\rm Y}{\rm Y},{\rm Y}J/\psi )$ in the improved color evaporation model via the parton Reggeization approach. The last one is based on high-energy factorization of hard processes in multi-Regge kinematics, the Kimber-Martin-Ryskin-Watt model for unintegrated parton distribution functions, and the Lipatov effective field theory of Reggezied gluons and quarks. We compare contributions from the single and double parton scattering mechanisms in the pair production of heavy quarkonia. The numerical calculations are performed with the Monte-Carlo event generator KaTie.
