“…To search for the possible critical energy in the phase transition from hadronic matter to QGP in high energy collisions, the STAR Collaboration has been performing the Beam Energy Scan (BES) program [10,11,12,13] at the RHIC. Besides, other experiments at similar or lower energies at other accelerators are scheduled [14,15].…”

Based on the data-driven analysis, the mid-rapidity transverse momentum (p T ) spectra of charged hadrons (π + , K + and p) produced in central and peripheral gold-gold (Au-Au) collisions from the Beam Energy Scan (BES) program at the Relativistic Heavy Ion Collider (RHIC) are fitted by the blast-wave model with Boltzmann-Gibbs statistics. The model result are in agreement with the experimental data measured by the STAR Collaboration at the RHIC-BES energies. We observe that the kinetic freeze-out temperature (T 0 ), transverse flow velocity (β T ), mean transverse momentum ( p T ), and initial temperature (T i ) increase with the collision energy and with the event centrality.

“…Over the past few years, there have been numerous efforts to explore a quantum chromodynamics (QCD) phase diagram and quark gluon plasma, which are important goals for ultra-relativistic heavy-ion collision experiments [1][2][3][4][5][6][7][8][9]. A QCD phase diagram is characterized by temperature (T ) and the baryon chemical potential (µ B ) [5,10].…”

A system size scan program was recently proposed for the STAR experiments at the Relativistic Heavy Ion Collider (RHIC). In this study, we employ a multiphase transport (AMPT) model for considering the bulk properties at the freeze-out stage for 10 B + 10 B, 12 C + 12 C, 16 O + 16 O, 20 Ne + 20 Ne, 40 Ca + 40 Ca, 96 Zr + 96 Zr, and 197 Au + 197 Au collisions at RHIC energies √ sNN of 200, 20, and 7.7 GeV. The results for 197 Au + 197 Au collisions are comparable with those of previous experimental STAR data. The transverse momentum pT spectra of charged particles (π ± , K ± , p, andp) at the kinetic freeze-out stage, based on a blast-wave model, are also discussed. In addition, we use a statistical thermal model to extract the parameters at the chemical freeze-out stage, which agree with those from other thermal model calculations. It was found that there is a competitive relationship between the kinetic freeze-out parameter T kin and the radial expansion velocity βT , which also agrees with the STAR or ALICE results. We found that the chemical freezeout strangeness potential µs remains constant in all collision systems and that the fireball radius R is dominated by NPart , which can be well fitted by a function of a NPart b with b ≈ 1/3. In addition, we calculated the nuclear modification factors for different collision systems with respect to the 10 B + 10 B system, and found that they present a gradual suppression within a higher pT range from small to large systems.be studied through the transverse momentum (p T ) spectra of the particles.

“…In ultra-relativistic heavy-ion collisions at BNL-RHIC and CERN-LHC, the quark-gluon plasma (QGP) is believed to be created [25][26][27][28][29][30][31][32]. Studying the properties of QGP is one of the main goals of these experiments.…”

Through 12 C + 197 Au collisions at √ sNN = 200 GeV using a multiphase transport (AMPT) model, the azimuthal angle dependences of the Hanbury Brown-Twiss (HBT) radii relative to the second-and third-order participant plane from π-π correlations are discussed. Three initial geometric configurations of 12 C, namely three-α-cluster triangle, three-α-cluster chain and Woods-Saxon distribution of nucleons, are taken into account, and their effects on the correlations are investigated. The ratio of the third-to the second-order HBT radii R 2 o(s),3 /R 2 o(s),2 is shown to be a clear probe for three configurations. In addition, this work presents the hadronic rescattering time evolution of the azimuthally dependent HBT radii. From the present study, one can learn that the HBT correlation from identical particles at freeze-out is able to provide the information of different initial configurations as collective flow proposed before.
