摘要
Prevalent models of multiparticle production in relativistic pp collisions at pre-LHC energies fail to provide convincing explanations of certain significant features of the final-state charged particles in high-multiplicity pp events at the LHC. In this article we study these features-which are usually interpreted as the collective behavior of particle production in relativistic heavy-ion collisions-in the framework of the hydrodynamic EPOS3 model, emphasizing a quantitative comparison between the data and model-based simulations in the same kinematic ranges for better understanding of the data. The work reveals a quantitative mismatch between the data and the model.
