The large values and constituent-quark-number scaling of the elliptic flow of low-pT D mesons imply that charm quarks,initially produced through hard processes,might be partially thermalized through strong interactions with quark-gluon plasma(QGP)in high-energy heavy-ion *** quantify the degree of thermalization of low-pT charm quarks,we compare the D^(0)meson spectra and elliptic flow from a hydrodynamic model to experimental data as well as transport model *** use an effective charm chemical potential at the freeze-out temperature to account for the initial charm quark production from hard processes and assume that they are thermalized in the local comoving frame of the medium before freeze-out.D^(0)mesons are sampled statistically from the freeze-out hyper-surface of the expanding QGP as described by the event-by-event(3+1)D viscous hydrodynamic model *** the hydrodynamic and transport models can describe the elliptic flow of D^(0)mesons at pT~3 GeV/c as measured in Au+Au collisions at√SNN=200 *** the experimental data on D^(0)spectra are consistent with the hydrodynamic result at small pT~1 GeV/c,they deviate from the hydrodynamic model at high transverse momentum,pT~2 GeV/*** diffusion and parton energy loss mechanisms in the transport model can describe the measured spectra reasonably well within the theoretical *** comparative study indicates that charm quarks only approach local thermal equilibrium at small pT,even though they acquire sizable elliptic flow comparable to light-quark hadrons at both small and intermediate pT.

Heavy-ion collisions at very high colliding energies are expected to produce a quark-gluon plasma(QGP) at the highest temperature obtainable in a laboratory setting. Experimental studies of these reactions can provide an unprecedented range of information on properties of the QGP at high temperatures. We report theoretical investigations of the physics perspectives of heavy-ion collisions at a future high-energy collider. These include initial parton production, collective expansion of the dense medium, jet quenching,heavy-quark transport, dissociation and regeneration of quarkonia, photon and dilepton production. We illustrate the potential of future experimental studies of the initial particle production and formation of QGP at the highest temperature to provide constraints on properties of strongly interaction matter.

Induced Photon and Dilepton Radiation in Medium

Single-cell omics: experimental workflow, data analyses and applications

Hard processes are considered good tools to study ultra-relativistic heavy-ion collision because they happen early in the reaction processes and thus can probe the early stage of the evolution of dense system, during which a quark-gluon plasma (QGP) could exist for a short period of time. Among the proposed hard probes, large transverse momentum jets or partons are especially useful because they interact strongly with the medium. Jet quenching due to the medium-induced radiative energy loss of a high-energy parton propagating through a dense medium can provide important information on the properties of the probable QGP phase. Thus, of particular importance is the calculation of the parton jet energy loss caused by the induced particle radiation.
