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.…”

“…The ALICE collaboration have published the R AA spectra of pions, kaons and protons (the resonances K * 0 and φ) at 0-5%, 5-10%, 10-20%, 20-40%, 40-60% and 60-80% (0-5%, 5-10%, 20-30% and 40-50%) centralities in Pb-Pb collisions at 2.76 TeV in refs. [25,26]. Here, the pion, kaon, proton and K * 0 spectra respectively refer to the spectra of π + +π − , K + + K − , p +p and K * 0 +K * 0 .…”

“…In ref. [31], the ALICE collaboration have published the p T spectra of pions, kaons and protons at 0-5%, 5-10%, 10-20%, 20-40%, 40-60% and 60-80% centralities p-Pb collisions at 5.02 TeV. Moreover, they also presented the p T spectra of these particles in pp collisions at this energy.…”

“…[32]. The ALICE collaboration have also published the p T spectra of K * 0 , φ, Λ, Ξ and Ω at different centralities in p-Pb collisions at 5.02 TeV [33,34,35]. However, the p T spectra of these particles in pp collisions at this energy are not available so far.…”

“…The energy loss can be investigated via the study of the difference of the transverse momentum (p T ) spectrum in heavy-ion collisions compared to that in proton-proton (pp) collisions at the same energy. The difference is quantified by the nuclear modification factor R AA(pA) , which is defined as [3,4] R AA(pA) (p T ) = 1 N coll…”
