“…In the present analysis we therefore kept to the basic structure of the thermal model with a single freeze-out temperature and focus on the resulting thermal parameters T ch , γ s and the radius. All our calculations were done using the latest version of THERMUS [24] [25].…”

Comparison of p−p, p−Pb , and Pb-Pb collisions in the thermal model: Multiplicity dependence of thermal parameters

An analysis is made of the particle composition (hadrochemistry) of the final state in protonproton (p-p), proton-lead (p-Pb) and lead-lead (Pb-Pb) collisions as a function of the charged particle multiplicity (dN ch /dη). The thermal model is used to determine the chemical freeze-out temperature as well as the radius and strangeness saturation factor γs. Three different ensembles are used in the analysis namely, the grand canonical ensemble, the canonical ensemble with exact strangeness conservation and the canonical ensemble with exact baryon number, strangeness and electric charge conservation. It is shown that for high multiplicities (at least 20 charged hadrons in the mid-rapidity interval considered) the three ensembles lead to the same results.

“…Since no unambiguous temperature can be assigned to this transition, the question arises whether hadrons of different quark composition freeze-out simultaneously or exhibit a flavor hierarchy [2]. This question is relevant since the reported strangeness enhancement at SPS, RHIC and LHC energies (in particular in the multi-strange particle sector [3][4][5]), and the discovery of hypernuclei formation at RHIC [6] suggest the possibility of increased strange bound state production at the highest available collision energies. Furthermore, recent measurements in relativistic heavy-ion collisions at the LHC indicate a separation of chemical freeze-out temperatures between light and strange quark hadrons [7,8].…”

Is There a Flavor Hierarchy in the Deconfinement Transition of QCD?

et al. 2013

We present possible indications for flavor separation during the QCD crossover transition based on continuum extrapolated lattice QCD calculations of higher order susceptibilities. We base our findings on flavor-specific quantities in the light and strange quark sector. We propose a possible experimental verification of our prediction, based on the measurement of higher order moments of identified particle multiplicities. Since all our calculations are performed at zero baryochemical potential, these results are of particular relevance for the heavy-ion program at the LHC.

“…The maximum R C P of three hadrons are all much larger than unity, which indicates that the initial state effects, such as the Cronin effect [13], might be dominant at these two energies. S can be used to make a comparison of baryon enhancement at higher energies [14], due to the large net-baryon density at mid-rapidity at these lower energies. As shown in Fig.…”
