报告摘要:
Heavy quarks are powerful tools for the study of the properties of the high-density QCD medium created in heavy-ion collisions as they are sensitive to the transport properties of the medium and may interact with the QCD matter differently from light quarks. As the main observables to study the medium effect, nuclear modification factors (RAA) and azimuthal anisotropy coefficients (vn) of heavy-flavor particles provide insights into the flavor dependence of in-medium parton energy loss and diffusion of heavy quarks in the bulk medium, and the production of heavy-flavor particles in jets is sensitive to the gluon splitting and the role of medium response. On the other hand, the measurement of the production of heavy-flavor baryons and strange heavy-flavor mesons is crucial to study harmonization mechanism in heavy-ion collisions.
Over the past few years, using the large statistics proton-proton and PbPb samples collected at 5.02 TeV, high precision measurements of heavy-flavor hadrons have been performed with the CMS detector. In this talk, the results of open heavy flavor particle RAA and vn, the study of hadronization of heavy quarks, and the measurement of heavy quark production in jets are presented.
