Charmed nuclei and exotic charmed meson production at CBM@FAIR and ALICE@LHC

TL;DR

This paper predicts the production rates of exotic charmed hadrons and nuclei in heavy-ion collisions at CBM@FAIR and LHC, highlighting CBM's potential to explore these states despite lower overall charm production.

Contribution

It introduces a combined modeling approach to estimate exotic charmed hadron and nucleus production rates at different collider energies, emphasizing CBM's unique exploration capabilities.

Findings

CBM can produce charmed states at rates detectable within seconds to minutes.

Charmed nuclei, if they exist, are predicted to be as abundant at CBM as at LHC.

Production rates vary significantly between CBM and LHC energies.

Abstract

We make predictions for the expected multiplicities of exotic charmed hadrons and charmed nuclei in Au+Au collisions at SIS100 and LHC beam energies, using input on light hadron and charm production from the UrQMD transport model, and applying the Thermal-FIST model. We demonstrate that the CBM experiment has the capability to explore these states with production rates of one per 3 seconds for $\chi_{c0}(1P)$ and $\chi_{c1}(1P)$, and one every 3 minutes for $X(3872)$ at the expected data taking rates. Due to the higher baryon density at CBM compared to the LHC, charmed nuclei, if they exist, will be equally abundant at CBM as at the LHC, even though the total charm production at CBM is much lower.
