# Transverse momentum distributions of charmonium states with the statistical hadronization model

## TL;DR

This paper uses the statistical hadronization model to predict transverse momentum spectra of charmonium states in heavy-ion collisions, showing good agreement with data and providing new predictions for the exotic state X(3872).

## Contribution

It introduces detailed predictions for charmonium transverse momentum distributions, including the exotic X(3872), within the statistical hadronization framework at LHC energies.

## Key findings

- Good agreement with existing data for J/ψ and ψ(2S) spectra.
- Predicted shape and yield for X(3872) in Pb-Pb collisions.
- Enhanced low transverse momentum production for X(3872).

## Abstract

Calculations and predictions are presented within the framework of the statistical hadronization model for transverse momentum spectra of the charmonium states J/$\psi$, $\psi(2S)$ and $X(3872)$ 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 $X(3872)$ production in Pb-Pb collisions we predict a transverse momentum distribution similar in shape to that for J/$\psi$ with a strong enhancement at low transverse momenta and a production yield of about 1\% relative to that for J/$\psi$.
