Heavy flavors under extreme conditions in high energy nuclear collisions

Understand

Heavy flavor hadrons have long been considered as a probe of the quark gluon plasma created in high energy nuclear collisions.

• In this paper we review the heavy flavor properties under extreme conditions and the realization in heavy ion experiments.
• After a short introduction on heavy flavor properties in vacuum, we emphasize the cold and hot nuclear matter effects on heavy flavors, including shadowing effect, Cronin effect and nuclear absorption for the former and Debye screening and regeneration for the latter.
• Then we discuss, in the frame of transport and coalescence models, these medium induced changes in open and closed heavy flavors in nuclear collisions and the comparison with nucleon-nucleon collisions.
