Description
We perform a systematic study on heavy quark dynamics in relativistic heavy-ion collisions.
The dynamical evolution of heavy quarks interacting with the quark-gluon plasma (QGP) is simulated via our new QLBT model, which improves the linearized Boltzmann transport (LBT) model by treating the QGP as a collection of quasi-particles.
To account for the non-perturbative interactions among quarks and gluons of the hot QGP, the thermal masses of quasi-particles are fitted to decribe the equation of state from lattice QCD simulations using the Bayesian statistical analysis method.
Combining QLBT model with our advanced hybrid fragmentation-coalescence hadronization approach, we calculate the nuclear modification factor $R_{AA}$ and the elliptic flow $v_2$ of $D$ mesons at RHIC and the LHC.
By comparing our state-of-the-art QLBT model calculation with the experimental data on $D$ meson $R_{AA}$ and $v_2$, we extract the heavy quark diffusion coefficient $D_s$ in the temperature range of $1-4~T_c$ and compare to the values from other groups.
