Centrality Evolution of Transverse Momentum Spectra of Identified Light-Flavor Hadrons in p+Pb Collisions at \(√{sₙₙ}\) = 5.02 TeV at the LHC Within a Two-Component Model

Using the two-component Tsallis-Hagedorn Model with Transverse Flow (THMTF), this study analyzes centrality dependencies of midrapidity transverse momentum (pT) spectra for identified light-flavor hadrons in asymmetric p+Pb collisions at Snn = 5.02 TeV, comparing them with symmetric Pb+Pb collision data at Snn = 2.76 and 5.02 TeV at the LHC. The analysis successfully describes ALICE experimental data up to pT = 20 GeV/c across seven multiplicity classes in p+Pb collisions, estimating that collective flow emerges at ⟨Npart⟩ ≈ 4.0 ± 0.5 along with simultaneous transitioning of kinetic freeze-out temperature to a nearly plateau region. The kinetic freeze-out temperature parameter shows distinct, system-dependent behavior before stabilization with an increase in ⟨ Npart⟩ in p+Pb and Pb+Pb collisions at the LHC. Furthermore, the findings suggest that collective flow and particle production correlate with increased thermalization, with spectral analysis indicating different dynamics at hard pT region between p+Pb and Pb+Pb collision systems.
