报告摘要:
Quark-Gluon Plasma (QGP) is a deconfined state of strong interaction matter that has been predicted by first-principle lattice QCD to emerge at extreme temperatures and densities. While having presumably filled up the primordial Universe a few microseconds after the Big Bang, QGP is being re-created and studied in terrestrial labs through relativistic heavy-ion collision experiments conducted at RHIC of Brookhaven National Lab and the LHC of CERN.
Heavy quarks, produced in the early stage through hard processes and experiencing the full evolution history of QGP through diffusion and hadronization, serve as valuable probes of the QGP properties. Likewise, heavy quark and antiquark bound states (quarkonium) are subjected to dissociation and regeneration in the hot QGP, making another kind of premier diagnostic tool of QGP. In this talk, the speaker will present some recent research on the heavy quark and heavy quarkonium probes of QGP, with the first part focusing on theoretical computations of heavy quarkonium dissociation rate, and the second part devoted to phenomenological development of charm-hadron production.
