D^0-Meson R_(AA) in PbPb Collisions at √s_(NN) = 5.02 TeV and Elliptic Flow in pPb Collisions at √s_(NN) = 8.16 TeV with CMS


The study of charm production in heavy-ion collisions is considered an excellent probe for the properties of the hot and dense medium created in heavy-ion collisions. Measurements of D^0-meson nuclear modification factor can provide strong constraints into the mechanisms of in-medium energy loss and charm flow in the medium. The measurement of D^0-meson elliptic flow in pPb collisions helps us understand the strength of charm quarks coupling to significantly reduced systems which demonstrate hydrodynamic properties. In this paper, the measurements of the D^0-meson nuclear modification factor in PbPb collisions at 5.02 TeV together with the new measurement of D^0-meson elliptic flow in high multiplicity pPb collisions at 5.02 TeV using the two-particle correlation method will be presented.
