Azimuthal angular correlations of D mesons with charged particles in pp collisions at √s = 7 TeV and p-Pb collisions at √s = 7 TeV and p-Pb collisions at √S _NN = 5.02 TeV with the ALICE experiment at the LHC

摘要

Heavy flavour studies played an important role in the understanding of energy loss in the formed medium in heavy-ion collisions through different observables (the nuclear modification factor R_(AA), the elliptic flow v_(2)). In this paper, results on heavy-flavour correlations will be presented. This observable is sensitive to the fragmentation processes of heavy flavours as well as the system of the collisions. First, the reason why studies on correlations are interesting will be discussed. The ALICE experimental step will be presented. Then the analysis strategy is explained. Finally, the results are presented.
