Description
Parallel session freeze-out
The standard implementation of the statistical model assumes point-like particles, and accounts for attractive interactions among hadrons through resonance formation.
The classical HRG model has proven to be unable to describe all the available results on fluctuations of B/Q/S conserved charges from lattice calculations, and shows some significant deviations from the latest measurements...
The conventional approach to treat strangeness freezeout has been to consider a unified freezeout scheme where strangeness freezes out along with the non-strange hadrons (1CFO), with or without an additional parameter accounting for out of equilibrium
strangeness production ($\gamma_S$). Several alternate scenarios have been formulated lately- i. to consider a hadronic afterburner post...
We present results from the Rope Hadronization model, implemented in the DIPSY Monte Carlo event generator, specifically regarding production of strangeness in small systems. The Rope Hadronization model is built on the Lund String Hadronization model. It allows for interactions between strings in dense environments. The interacting strings form "colour ropes", characterized by their SU(3)...
The string melting version of a multi-phase transport model is often applied to high energy heavy ion collisions since the formed dense matter is expected to be in parton degrees of freedom. In this work we improve its quark coalescence component, which describes the hadronization of the partonic matter to a hadronic matter. We have removed the previous constraint that forced the numbers of...
We investigate the fate of the light baryons in the hadronic and the quark-gluon plasma. In the confined phase a strong temperature dependence is seen in the masses of the negative-parity groundstates, while at high temperature parity doubling emerges. We study baryons with different strangeness and find a noticeable effect of the heavier s quark. This study uses nonperturbative lattice...
Extension of the ideal hadron resonance gas (HRG) model is constructed which includes attractive and repulsive van der Waals (VDW) interactions between hadrons [1]. The model employs a novel multi-component quantum statistical VDW approach which incorporates the Fermi-Dirac and Bose-Einstein effects in the system of interacting particles.
The VDW parameters a and b are fixed by the ground...
We present several results on the temperature dependence of hadronization and hadron freeze out by using different approaches. We apply the Polyakov-Nambu-Jona-Lasinio model to generate the low-lying mesons and baryons with strangeness at finite temperature. We find a flavor-dependent pattern in the temperature of the effective deconfinement, similarly to what is found in recent lattice...
The identified hadron spectra measured in high energy particle collisions are one of the most fundamental observable quantities. They accumulate information about all the processes during the collisions. They may carry information about all the microscopical and collective processes which occur during high-energy collisions, therefore it is essential to measure and analyze them as precise as...
The ALICE experiment has measured a variety of (anti-)(hyper-) nuclei produced in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV and at 2.76 TeV. In addition, a large sample of high quality data was recorded in pp collisions at $\sqrt{s} = 7$ TeV and 13 TeV and in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5 TeV. These data are used to study the production of a variety of...
