Nuclear modification factor in Pb–Pb and p-Pb collisions using Boltzmann transport equation

“…(iii) T eq decreases with centrality. This trend is similar to that of the kinetic freezeout temperature T kin returned from the combined blast-wave fit on the pion, kaon and [25,26,27,28,36,37]. The curves represent the combined fit.…”

“…For the Λ R AA spectra, no official data are released so far. However, the ALICE collaboration have presented the Λ p T spectra at 0-5%, 5-10%, 10-20%, 20-40%, 40-60% and 60-80% centralities in Pb-Pb collisions at this energy [27]. Moreover, the preliminary result of the Λ p T spectra in pp collisions at 2.76 TeV is available [28].…”

Tsallis-thermometer: a QGP indicator for large and small collisional systems

“…These distributions are measured by complex detector systems such as the ALICE, CMS, ATLAS and LHCb at the LHC (CERN, Switzerland) or PHENIX, STAR, BRAHMS and PHOBOS at the RHIC (BNL, USA). Recently, phenomena, interpreted as being the sign of QGP formation, were measured in small collisional systems, such as pPb and high-multiplicity pp collisions [1][2][3][4][5][6][7][8][9][10][11][12][13]. With the discovery of the strong correlations in these systems the dominance of the hydrodynamic description became uncertain [8].…”

Sensitivity analysis for observables of the chiral magnetic effect using a multiphase transport model

“…chiral magnetic effect [10][11][12][13][14]. The transitional observable to detect the CME is a charge-dependent azimuthal correlator, γ = cos(φ α + φ β − 2Ψ RP ) , which has been widely investigated both experimentally and theoretically [15][16][17][18][19][20][21]. Unfortunately, the observable can not distinguish the CME signal from the large background clearly [22][23][24][25][26][27][28][29], because many kinds of backgrounds can contribute to γ [25,27].…”
