We study the production of heavy multiquark states in the heavy ion collisions performed at the LHC. We assume that they are produced at the end of the quark-gluon plasma phase and then interact with light hadrons during the hadron gas phase. We use the coalescence model to compute the initial multiplicities and effective Lagrangians to describe the interactions. We find that the initial multiplicity of molecules is two orders of magnitude larger than that of tetraquarks. The interactions in the hadron gas reduce the number of molecules and increase the number of tetraquarks by a factor two in each case. At kinetic freeze-out, the difference is still very large.

  1. Absorption of $\psi(2S)$ mesons in nuclei

    nucl-th 2025-02 conditional novelty 4.0 of 10

    Near-threshold photoproduction of ψ(2S) mesons on nuclei is predicted to show measurable sensitivity to the unknown ψ(2S)-nucleon absorption cross section, motivating measurements at an upgraded CEBAF.
