  We study the transverse momentum spectra of identified pions, Kaons, protons
and Lambdas produced at midrapidity (0 < y < 0.5)in most central p-Pb
collisions at root(sNN) = 5.02 TeV in comparison with a Unified Statistical
Thermal Freeze-out Model (USTFM). The measurements of pions are reported upto
pT = 3 GeV, the kaons (K- + K+) are reported upto pT = 2.5 GeV, K0s is reported
upto pT = 7 GeV and the baryons (protons and Lambdas) are reported upto pT =
3.5 GeV. A good agreement is seen between the calculated results and the
experimental data points taken from the ALICE experiment. The transverse
momentum spectra are found to be flatter for heavy particles than for light
particles. Bulk freeze-out properties in terms of kinetic freezeout temperature
and the transverse collective flow velocity are extracted from the fits of the
transverse momentum spectra of these hadrons. The effect of resonance decay
contributions has also been taken care of.
