Description
Heavy quark provides an excellent prob of the hot dense medium created in ultra-relativistic heavy-ion collisions due to its larger masses. The heavy flavor quark are dominantly produced before the quark-gluon plasma (QGP) formation and then transport in the medium and hadronization when the medium is cooling down. Measurements of open heavy flavor hadron production in ultra-relativistic heavy-ion collisions can be used study the QGP properties. While the production of hidden heavy flavor (quarkonium) is expected to be suppressed in ultra-relativistic heavy-ion collisions due to the color-screening of the potential of heavy quark and its anti-quark and has been proposed as smoking-gun signal of QGP formation.
Recent years, thanks to the newly installed Heavy Flavor tracker (HFT) and Muon Telescope Detector (MTD) detectors, RHIC-STAR experiment has achieved a serious high quality data on the open and hidden heavy flavor production in ultra-relativistic heavy-ion collisions. In this talk, I will review these experimental results. Physics implications will also be discussed.
