| contents | Transverse momentum spectra of identified pions, Kaons , protons and Lambdas produced at mid-rapidity (0 < ycm < 0.5) in p-Pb collisions at root(sNN) = 5.02 TeV is studied for different collision centralities by using a Unified Statistical Thermal Freeze-out Model (USTFM). A fairly good agreement is seen between the calculated results and the experimental data points taken from the ALICE experiment. Kinetic freeze-out conditions are extracted from the fits of the transverse momentum spectra of these hadrons for each centrality class. A comparison of the obtained freeze-out parameters with those of heavy-ion collisions (Pb + Pb) is made and discussed. |
