Using the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model, we investigate the azimuthal correlations in p–Pb collisions at √sNN = 5.02 TeV. It is shown that the simulated hadronic p–Pb system can not generate the collective flow signatures, but mainly behaves as a non-flow dominant system. However, the characteristic υ2(pT) mass-ordering of pions, kaons and protons is observed in UrQMD simulations, which is the consequence of hadronic interactions and not necessarily associated with strong fluid-like expansions.
