“…Hence, the study of heavy quark transport coefficients in the QGP medium is a field of high contemporary interest, see Refs. [19][20][21][22][23] for the recent studies. The two dominant processes that contribute to the energy loss of heavy quark in the medium are namely, the collisional (elastic interaction) and the inelastic interactions like gluon bremsstrahlung [24][25][26][27][28][29][30].…”

“…The effect of non-equilibrium dynamics of the QGP has already been explored in photon production, dilepton emission, heavy quarkonia, and other associated physical observables at the RHIC and LHC [47][48][49][50][51][52]. Recently, some works have been done to analyse the effects of shear and bulk viscous coefficients on heavy quark transport in the expanding medium [21,[53][54][55][56].…”

The impact of momentum anisotropy on the heavy quark transport coefficients due to collisional and radiative processes in the QCD medium has been studied within the ambit of kinetic theory. Anisotropic aspects (momentum) are incorporated into the heavy quark dynamics through the non-equilibrium momentum distribution function of quarks, antiquarks, and gluons. These non-equilibrium distribution functions that encode the physics of momentum anisotropy and turbulent chromo-fields have been obtained by solving the ensemble-averaged diffusive Vlasov-Boltzmann equation. The momentum dependence of heavy quark transport coefficients in the medium is seen to be sensitive to the strength of the anisotropy for both collisional and radiative processes. In addition, the collisional and radiative energy loss of the heavy quark in the anisotropic hot QCD medium have been analyzed. The effects of anisotropy on the drag and diffusion coefficients may have a visible impact on the measured observables associated with heavy quarks, such as the nuclear suppression factor and flow coefficients in high-energetic heavy-ion collisions at the RHIC and LHC.

Heavy quark dynamics in an anisotropic QCD medium have been analyzed within the Fokker-Planck approach. Heavy quark drag force and momentum diffusion tensor have been decomposed by employing a general tensor basis for an anisotropic medium. Depending upon the relative orientation of the direction of the momentum anisotropy of the medium and heavy quark motion, two drag and four diffusion coefficients have been estimated in the anisotropic QCD medium. The relative significance of different components of drag and momentum diffusion coefficients has been explored. The dependence of the angle between the anisotropic vector and heavy quark motion to the drag and diffusion coefficients has also been studied. Further, the energy loss of heavy quarks due to the elastic collisional process in an anisotropic medium has been studied. It is seen that the anisotropic contributions to heavy quark transport coefficients and its collisional energy loss have a strong dependence on the direction and strength of momentum anisotropy in the QCD medium.

We study the momentum and temperature dependence of the charm quark transport coefficients, i.e., drag and momentum diffusion for collisional and radiative processes in a viscous QCD medium. The thermal medium interactions are included through the effective fugacity quasiparticle model, which modifies the distribution function of the QGP particles by the introduction of temperature-dependent effective fugacity parameter. Shear viscous corrections to the charm quark transport coefficients are incorporated at leading order through the near-equilibrium distribution function by solving the effective Boltzmann equation within relaxation time approximation. Preliminary results for bulk viscous corrections are also presented within the same framework.
