“…For open charmed mesons, the results with ε = 1 decrease about 30% compared to those with ε = 0. The predicted yield of Ω ++ ccc is in good agreement with the result from the coalescence model [41]. The computed results for the other charmed hadrons wait for the comparisons with the future experimental measurements and/or other theoretical calculations.…”

In the framework of the quark combination, we derive the yield formulas and study the yield ratios of the hidden-charm pentaquark states in ultra-relativistic heavy ion collisions. We propose some interesting yield ratios which clearly exhibit the production relationships between different hidden-charm pentaquark states. We show how to employ a specific quark combination model to evaluate the yields of exotic P + c (4380), P + c (4450) and their partners on the basis of reproducing the yields of normal identified hadrons, and execute the calculations in central Pb+Pb collisions at √ s NN = 2.76 TeV as an example.

“…This contribution is significantly enhanced when charm quark densities become large in QGP. Both theoretical and experimental studies have suggested that this coalescence process becomes essential in the charmonium and multi-charm hadron production at the LHC [20][21][22][23][24][25][26][27]. The coalescence model and statistical hadronization model have been extended to study the hadron production in heavy-ion collisions [28][29][30][31][32].…”

Heavy ion collisions provide a unique opportunity to study the nature of X(3872) compared with electron-positron and proton-proton (antiproton) collisions. With the abundant charm pairs produced in heavy-ion collisions, the production of multicharm hadrons and molecules can be enhanced by the combination of charm and anticharm quarks in the medium. We investigate the centrality and momentum dependence of X(3872) in heavy-ion collisions via the Langevin equation and instant coalescence model (LICM). When X( 3872) is treated as a compact tetraquark state, the tetraquarks are produced via the coalescence of heavy and light quarks near the quantum chromodynamic (QCD) phase transition due to the restoration of the heavy quark potential at T → T c . In the molecular scenario, loosely bound X(3872) is produced via the coalescence of D 0 -D * 0 mesons in a hadronic medium after kinetic freeze-out. The phase space distributions of the charm quarks and D mesons in a bulk medium are studied with the Langevin equation, while the coalescence probability between constituent particles is controlled by the Wigner function, which encodes the internal structure of the formed particle.First, we employ the LICM to explain both D 0 and J/ψ production as a benchmark. Then, we give predictions regarding X(3872) production. We find that the total yield of tetraquark is several times larger than the molecular production in Pb-Pb collisions. Although the geometric size of the molecule is huge, the coalescence probability is small due to strict constraints on the relative momentum between D 0 and D * 0 in the molecular Wigner function, which significantly suppresses the molecular yield.

“…In [8], hadronic production cross-sections of the baryons with the ccc and ccb quark content were estimated with a conclusion that around 10 4 -10 5 events of triply-heavy baryons can be accumulated for 10 fb −1 integrated luminosity at LHC. The production of ccc baryon by quark coalescence mechanism in high energy nuclear collisions was studied in [9] and nuclear medium effect on multicharmed baryon production was studied in [10]. Both of these two studies presented that it is most probable to observe triply-heavy baryon in heavy ion collisions.…”
