We investigate the nuclear modification factor (R AA ) of identified particles as a function of transverse momentum (p T ) in Pb-Pb collisions at √ s NN = 2.76 and 5.02 TeV, as well as p-Pb collision at 5.02 TeV in the framework of Boltzmann transport equation with relaxation time approximation. In this framework, the initial distribution of particles is chosen as the Tsallis distribution and the local equilibrium distribution as the Boltzmann-Gibbs blast-wave distribution. The nonextensive parameter q pp , the Tsallis temperature T pp and the equilibrium temperature T eq are set to be in common for all particles, while the ratio of kinetic freeze-out time to relaxation time t f /τ is different for different particles when we performed a combined fit to the R AA spectra of different particles at a given centrality. We observe that the fitted curves describe the spectra well up to p T ≈ 3 GeV/c. q pp and T eq (t f /τ ) decrease (increases) with centrality nonlinearly, while T pp is almost independent of centrality. The dependence of the rate at which q pp , T eq or t f /τ changes with centrality on the energy and the size of the colliding system is discussed.

Charmed hadrons from coalescence plus fragmentation in relativistic nucleus-nucleus collisions at RHIC and LHC

et al. 2018

View full text Add to dashboard Cite

In a coalescence plus fragmentation approach we calculate the heavy baryon/meson ratio and the pT spectra of charmed hadrons D 0 , Ds and Λ + c in a wide range of transverse momentum from low pT up to about 10 GeV and discuss their ratios from RHIC to LHC energies without any change of the coalescence parameters. We have included the contribution from decays of heavy hadron resonances and also the one due to fragmentation of heavy quarks which do not undergo the coalescence process. The coalescence process is tuned to have all charm quarks hadronizing in the pT → 0 limit and at finite pT charm quarks not undergoing coalescence are hadronized by independent fragmentation. The pT dependence of the baryon/meson ratios are found to be sensitive to the masses of coalescing quarks, in particular the Λc/D 0 can reach values of about 1 ÷ 1.5 at pT ≈ 3 GeV, or larger, similarly to the light baryon/meson ratio like p/π and Λ/K, however a marked difference is a quite weak pT dependence with respect to the light case, such that a larger value at intermediate pT implies a relatively large value also for the integrated yields. A comparison with other coalescence model and with the prediction of thermal model is discussed.

Insight into Multiple Partonic Interactions and Production of Charmonia in $$p+p$$ Collisions at the LHC Energies

At the LHC energies, the underlying observables are of major topic of interest in high multiplicity p + p collisions. Multiple Parton Interactions (MPIs) is one of them, in which several interactions occur in a single p + p collision. It is believed that MPI is the main reason behind the high multiplicity in p + p collisions at the LHC. It was believed that MPI has only effect to the soft particle production, but recent ALICE result reveals that it can also affect the hard-particle production. In such case, the self normalized yield of heavy particle like J/ψ show increase trend with event multiplicity. In the present contribution, we discuss the energy and multiplicity dependence of charmonium production to understand the effects of MPI on charmonium production.
