“…We see that there is a stronger suppression in more central collisions in the p T range 4 GeV < p T < 10 GeV. Figure 4b shows f Here, T AA is the average nuclear overlap function [31], dσ pp c /dy is the p T integrated cross-section of charm quarks in pp collisions which is about 1.0 mb at √ s = 5.02 TeV [77]. The values of dN c /dy at different centralities are listed in Table 2.…”

Using a quark combination model with the equal-velocity combination approximation, we study the production of hadrons with strangeness and charm flavor quantum numbers in Pb+Pb collisions at sNN= 5.02 TeV. We present analytical expressions and numerical results for these hadrons’ transverse momentum spectra and yield ratios. Our numerical results agree well with the experimental data available. The features of strange and charm hadron production in the quark–gluon plasma at the early stage of heavy ion collisions are also discussed.

“…[37] to explain the constituent quark number scaling (QNS) property that we found in the experimental data of p T spectra of identified hadrons in pPb collisions at LHC energy. The model is now applied to pp, pA and AA collisions at both RHIC and LHC energies, and has successfully explained the experimental data for yields, p T spectra and elliptic flow of light-flavor hadrons and those of single-charm hadrons at RHIC and LHC [38][39][40][41][42][43][44][45].…”

We compile experimental data for the averaged transverse momentum ( pT ) of proton, Λ, Ξ − , Ω − and φ at mid-rapidity in Au+Au collisions at 200, 39, 27, 19.6, 11.5, 7.7 GeV and in Pb+Pb collisions at √ sNN = 2.76 TeV, and find that experimental data of these hadrons exhibit systematic correlations. We apply a quark combination model with equal-velocity combination approximation to derive analytic formulas of hadronic pT in the case of exponential form of quark pT spectra at hadronization. We use them to successfully explain the systematic correlations exhibited in pT data of pΛ, ΛΞ − , Ξ − Ω − and Ξ − φ pairs. We also use them to successfully explain the regularity observed in pT of these hadrons as the function of (dN ch /dy)/(0.5Npart) at mid-rapidity in central heavy-ion collisions at both RHIC and LHC energies. Our results suggest that the constituent quark degrees of freedom and the equal-velocity combination of these constituent quarks at hadronization play an important role in understanding pT correlations of baryons and φ meson in heavy-ion collisions at these RHIC and LHC energies.

The study of heavy-flavour mesons and baryons in hadronic collisions provides unique access to the properties of heavy-quark hadronisation in the presence of large partonic densities, where new mechanisms of hadron formation beyond in-vacuum fragmentation can emerge. Performing these measurements in intervals of charged-particle multiplicities across different collision systems provides sensitivity to understand whether different hadronisation mechanisms are at play in small and large hadronic colliding systems. In this contribution, a selection of the latest charm and beauty production measurements in proton–proton (pp) collisions is presented, which can shed light on the modification of the heavy-quark hadronisation mechanisms with respect to leptonic collisions. New published results of the production of all prompt charm ground states in pp collisions at √S = 13 TeV, which allowed us to measure the charm fragmentation fractions and the total cc production cross section at midrapidity, will be shown. The new final measurement of non-prompt (i.e. originating from beauty-hadron decays) Λc+ baryons in the same collisions system will be discussed to provide a quantitative comparison between the hadronisation properties of beauty and charm hadrons. New measurements of Ξc0 production as a function of charged-particle multiplicity in pp collisions at √S = 13, and of Ξc0 production in p–Pb collisions at √SNN = 5.02 TeV, will be also presented, shedding further light on the hadronisation of charm-strange baryons in different colliding systems.
