“…We note that the Bc(bc, bc) and J/Ψ (cc) and more generally all bound cc states yields were calculated before in the kinetic formation and dissociation models [4,6]. Our present work suggests that it is important to account for the binding of heavy flavor with strangeness, an effect which depletes the eligible supply of heavy flavor quarks which could form Bc(bc, bc) and J/Ψ (cc) [7].…”

“…This value is also much larger than the prediction of the statistical hadronisation model [295], in which the hadronisation occurs by recombination of an equilibrated system of quarks and the hadron abundances are mainly determined by their masses. In addition, hadronisation via coalescence in a strangeness-rich Quark-Gluon Plasma is predicted to lead to a large enhancement in the production of strange heavy-flavour hadrons, like D s and B s [296][297][298]. Hints of an enhancement of the D s /D 0 and Λ c /D 0 ratios in nucleus-nucleus collisions have recently been reported by ALICE at the LHC [299,300] and by STAR at RHIC [301].…”

The future opportunities for high-density QCD studies with ion and proton beams at the LHC are presented. Four major scientific goals are identified: the characterisation of the macroscopic long wavelength Quark-Gluon Plasma (QGP) properties with unprecedented precision, the investigation of the microscopic parton dynamics underlying QGP properties, the development of a unified picture of particle production and QCD dynamics from small (pp) to large (nucleus-nucleus) systems, the exploration of parton densities in nuclei in a broad (x, Q 2 ) kinematic range and the search for the possible onset of parton saturation. In order to address these scientific goals, high-luminosity Pb-Pb and p-Pb programmes are considered as priorities for Runs 3 and 4, complemented by high-multiplicity studies in pp collisions and a short run with oxygen ions. High-luminosity runs with intermediate-mass nuclei, for example Ar or Kr, are considered as an appealing case for extending the heavy-ion programme at the LHC beyond Run 4. The potential of the High-Energy LHC to probe QCD matter with newly-available observables, at twice larger center-of-mass energies than the LHC, is investigated.

We report measurements of the production of prompt D 0 , D + , D * + and D + s mesons in Pb-Pb collisions at the centre-of-mass energy per nucleon-nucleon pair √ s NN = 5.02 TeV, in the centrality classes 0-10%, 30-50% and 60-80%. The D-meson production yields are measured at mid-rapidity (|y| < 0.5) as a function of transverse momentum (p T). The p T intervals covered in central collisions are: 1 < p T < 50 GeV/c for D 0 , 2 < p T < 50 GeV/c for D + , 3 < p T < 50 GeV/c for D * + , and 4 < p T < 16 GeV/c for D + s mesons. The nuclear modification factors (R AA) for non-strange D mesons (D 0 , D + , D * +) show minimum values of about 0.2 for p T = 6-10 GeV/c in the most central collisions and are compatible within uncertainties with those measured at √ s NN = 2.76 TeV. For D + s mesons, the values of R AA are larger than those of non-strange D mesons, but compatible within uncertainties. In central collisions the average R AA of non-strange D mesons is compatible with that of charged particles for p T > 8 GeV/c, while it is larger at lower p T. The nuclear modification factors for strange and non-strange D mesons are also compared to theoretical models with different implementations of in-medium energy loss.

Charmed hadrons from strangeness-rich QGP

Abstract: Abstract. The yields of charmed hadrons emitted by strangeness rich QGP are evaluated within chemical non-equilibrium statistical hadronization model, conserving strangeness, charm, and entropy yields at hadronization.
