A. Andronic, P. Braun-Munzinger, K. Redlich, J. Stachel
TL;DR
This paper examines charmonium production in nuclear collisions using the statistical hadronization model, successfully explaining RHIC data and predicting different behaviors at LHC energies, with limitations in elementary collisions.
Contribution
It applies the statistical hadronization model to charmonium production, providing new predictions for LHC energies and highlighting its limitations in elementary collisions.
Findings
Model reproduces RHIC data well.
Predicts different charmonium behavior at LHC depending on charm cross section.
Fails to reproduce measurements in elementary collisions.
Abstract
We discuss the production of charmonium in nuclear collisions within the framework of the statistical hadronization model. We demonstrate that the model reproduces very well the availble data at RHIC. We provide predictions for the LHC energy where, dependently on the charm production cross section, a dramatically different behaviour of charmonium production as a function of centrality might be expected. We discuss also the case in elementary collisions, where clearly the statistical model does not reproduce the measurements.
