Description
In order to understand how particle production mechanisms change with system size, proton-lead (p-Pb) collisions, with their charged particle multiplicity that is intermediate between proton-proton (pp) and lead-lead (Pb-Pb) collisions, are of crucial importance. Due to their relatively short lifetimes, resonances are good candidates to probe the existence of particle re-scattering and regeneration in hadronic phase, which may modify the yield of resonances measured in hadronic decay channel. Measurements of resonance particles ($K(892)^{0} , \Phi(1020),\Sigma(1385)^{\pm}$ and $\Xi(1530)^{0} $) produced in p-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV have been performed in the rapidity range $-0.5 < y < 0$ with the ALICE detector at the LHC. Resonance reconstruction, transverse momentum spectra, mean transverse momenta and particle ratios are presented and compared to model predictions.
