Abstract
Heavy flavour mesons are used as powerful tools for the study of the strongly interacting medium in heavy ion collisions as heavy quarks are sensitive to the transport properties of the medium. In these proceedings, D 0 nuclear modification factors, comparing the yields in PbPb and pp collisions, and azimuthal anisotropies in PbPb collisions are reported. Prompt D 0 mesons and their antiparticles have been measured with the CMS detector via the hadronic decay channels D 0 → K - π + and D 0 → K + π - in PbPb and pp collisions at a centre-of-mass energy of 5.02 TeV. Nonprompt D 0 from b quark decays are subtracted. The D 0 results are compared to inclusive charged particles, non-prompt J/ψ mesons from b decays and B + mesons in order to reveal possible meson mass dependence of the observables.
