Spectra and polarizations of prompt J/ψ at the NICA within collinear parton model and parton Reggeization approach

We study prompt production of J/ψ at the energy range of the NICA collider within the parton Reggeization approach (PRA) applying the non-perturbative QCD (NRQCD) factorization model for c c ¯ →J/ψ transition. We calculate transverse momentum distribution for direct J/ψ as well as for J/ψ from decay...

Summary:We study prompt production of J/ψ at the energy range of the NICA collider within the parton Reggeization approach (PRA) applying the non-perturbative QCD (NRQCD) factorization model for c c ¯ →J/ψ transition. We calculate transverse momentum distribution for direct J/ψ as well as for J/ψ from decays of higher-lying charmonium states. Production of polarized J/ψ is studied and parameter λθ as a function of transverse momentum is calculated. The comparison with predictions obtained in calculations based on the next-to-leading approximation of the collinear parton model is done.
