Description
Heavy quarks serve as a clean probe of the color-deconfined QGP matter produced in relativistic heavy-ion collisions. We develop a unified perturbative and non-perturbative Boltzmann transport model for studying the elastic and inelastic scatterings of heavy quarks inside the QGP. A generalized Cornell-type potential is implemented, which incorporates both the short-range Yukawa interaction and the long-range color confining interaction. By combining this new approach to a (3+1)-dimensional viscous hydrodynamic model for the QGP evolution and a hybrid fragmentation-coalescence model for heavy quark hadronization, we obtain a satisfactory description of nuclear modification of heavy flavor observables from low to intermediate to high transverse momenta. From the model-to-data comparison, we extract the in-medium heavy quark potential from open heavy flavor observables for the first time, which is shown in agreement with the lattice QCD calculation. And by combining this Boltzmann transport model with a quasi-particle description of the QGP, we perform a first extraction of the Equation of State of the QGP using the open heavy flavor data, which is shown consistent with the lattice QCD result as well.
