Transverse Momentum Distributions of Identified Particles in p-Pb Collisions at $\mathrm{\sqrt{s_{NN}} = 5.02\ TeV}$

Abstract: Transverse momentum ($p_{\mathrm{T}}$) distributions of identified hadrons produced in p-Pb collisions at $\mathrm{\sqrt{s_{NN}} = 5.02\ TeV}$ have been measured at mid-rapidity (0 $< y_{\mathrm{CMS}} <$ 0.5) by ALICE. Particle tracks are reconstructed using the central barrel detectors. Particle identification is performed via specific energy loss, time-of-flight or their characteristic decay topology over a wide transverse momentum range (0 GeV/c up to 8 GeV/c). Spectral shapes and particle ratios are measured in six multiplicity classes. They are compared with several model calculations and results from Pb-Pb collisions at $\mathrm{\sqrt{s_{NN}} = 2.76\ TeV}$ and pp collisions at $\mathrm{\sqrt{s_{NN}} = 7\ TeV}$ at the LHC. The results are discussed with respect to possible collective effects in p--Pb collisions.
