Transverse momentum distributions of charmonium states with the statistical hadronization model

Nuclear Theory 2019-08-23 v2

Abstract

Calculations and predictions are presented within the framework of the statistical hadronization model for transverse momentum spectra of the charmonium states J/ψ\psi, ψ(2S)\psi(2S) and X(3872)X(3872) produced in nucleus-nucleus collisions at LHC energies. The results are confronted with available data and exhibit very good agreement by using particle flow profiles from state-of-the-art hydrodynamic calculations. For X(3872)X(3872) production in Pb-Pb collisions we predict a transverse momentum distribution similar in shape to that for J/ψ\psi with a strong enhancement at low transverse momenta and a production yield of about 1\% relative to that for J/ψ\psi.
