Description
The heavy flavor(HF) quarks are produced in the initial hard scattering of heavy ion collisions. This allows us to access information from the very early stage of the collision and the intermediate stages, especially the strong interaction with the medium, supposedly created with a high density and temperature, so-called quark-gluon-plasma. The observed HF hadrons encapsulate the information, requiring comprehensive investigation to fully understand the underlying effects. In this talk, recent results on open HF measurements from CMS are presented. The nuclear modification factors of charm and beauty hadrons are compared in different system sizes to understand cold and hot nuclear matter effects. The correlation measurements of the open HF are also presented to allow us to investigate further specifics such as medium energy loss and the initial production mechanism. The results are compared with the model predictions.
