  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.
