Description
The heavy-flavour particles are produced in the earlier stage in heavy-ion collision and experience the full evolution of the QGP medium. The measurement of D mesons could provide us important inputs for flavour and charge dependent transport properties. On the other hand, with abundant strange quarks presented in heavy-ion collision, the $D_{S}^{+}$ production is expected to be enhanced hadronization via recombination. Large statistics proton-proton and PbPb samples collected at 5.02 TeV with CMS detector are used for the measurement of $D^{0}$ and $D_{S}^{+}$ production over a wide transverse momentum range. Result of D-meson $p_T$-differential cross section, nuclear modification factor $R_{AA}$, and the ratio of $D_{S}^{+}$ over $D^{0}$ for both pp and PbPb collisions are presented.
