Open Heavy Flavor Measurement in heavy ion collisions with CMS

The study of heavy quark production may reveal critical features of the medium produced in heavy ion collisions as heavy quarks are sensitive to the transport properties of the medium and may interact differently from light quarks. Non-prompt $J/\psi$ and b jet produced in both 5.02 TeV pPb as well as 2.76 TeV PbPb collision data have been measured with the CMS detector as a function of both rapidity and transverse momentum. Fully reconstructed B mesons in pPb data were also analyzed and along with these measurements, the nuclear modification factors constructed using either a theoretically calculated pp reference or CMS pp collision data will be presented for each analysis and collision systems.
