Is hadronic flow produced in p–Pb collisions at the Large Hadron Collider?
Using the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model, we investigate the azimuthal correlations in p–Pb collisions at √s NN = 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 υ 2 (p T ) 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.
