Contribution

It introduces a detailed analysis of double $J/\psi$ production in diffractive events at the LHC within the Resolved Pomeron framework, including color channel contributions.

Findings

Central diffractive processes contribute significantly to double $J/\psi$ production.

Predicted cross sections vary with rapidity and transverse momentum at LHC energies.

Study offers a way to test the Resolved Pomeron model experimentally.

Abstract

In this paper we study the double $J/\psi$ production in central diffractive processes considering the Resolved Pomeron model. Based on the nonrelativistic QCD (NRQCD) factorization formalism for the quarkonium production mechanism we estimate the rapidity and transverse momentum dependence of the cross section for the double $J/\psi$ production in diffractive processes at LHC energies. The contributions of the color-singlet and color-octet channels are estimated and predictions for the total cross sections in the kinematical regions of the LHC experiments are also presented. Our results demonstrate that the contribution of central diffractive processes is not negligible and that its study can be useful to test the Resolved Pomeron model.
