In relativistic nuclear collisions the production of hadrons with light (u,d,s) quarks is quantitatively described in the framework of the Statistical Hadronization Model (SHM). Charm quarks are dominantly produced in initial hard collisions but interact strongly in the hot fireball and thermalize. Therefore charmed hadrons can be incorporated into the SHM by treating charm quarks as 'impurities' with thermal distributions, while the total charm content of the fireball is fixed by the measured open charm cross section. We call this model SHMc and demonstrate that with SHMc the measured multiplicities of single charm hadrons in lead-lead collisions at LHC energies can be well described with the same thermal parameters as for (u,d,s) hadrons. Furthermore, transverse momentum distributions are computed in a blast-wave model, which includes the resonance decay kinematics. SHMc is extended to lighter collision systems down to oxygen-oxygen and includes doubly- and triply-charmed hadrons. We show predictions for production probabilities of such states exhibiting a characteristic and quite spectacular enhancement hierarchy.

Heavy quark coalescence probability in the presence of a potential
Including a phenomenological heavy-light quark potential in the coalescence model enhances the heavy-quark coalescence probability to near unity at low momentum without ad hoc normalization.

Out-of-equilibrium contributions to charm hadrons in a fluid-dynamic approach
Out-of-equilibrium corrections at initialization and freeze-out make computed charm-hadron yields independent of the charm diffusion coefficient and define the reliable transverse-momentum range.

What is the Quark-Gluon Plasma made of?
The quark-gluon plasma is best described as a strongly coupled liquid of massive, very short-lived quark and gluon quasiparticles, with sound (phonon) modes becoming the most well-defined collective excitation at low momenta.
