Centrality dependent long-range angular correlations of intermediate-p_T D-mesons and charged particles in pPb collisions at the LHC energy

The high-multiplicity events of pPb collisions at ${\sqrt{s}}_{NN}=5.02TeV$ at the LHC exhibit unforeseen collective behavior. One of the possible explanations to the collectivity could be the formation of thermalized partonic matter, like the one formed in relativistic nucleus–nucleus collisions and is described by the hydrodynamic models. This article presents a study on the centrality dependent long-range two-particle azimuthal correlations of D-mesons and charged particles in pPb collisions at ${\sqrt{s}}_{NN}=5.02TeV$. The study has been conducted on the events, generated with the EPOS3 hydrodynamic code that reproduces most of the features of the pPb data at the LHC energy. There appears a ridge-like structure in the long-range two-particle angular correlations of D-mesons, in the intermediate p _T-range, and charged particles in the simulated high-multiplicity pPb events.
