Abstract
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 are observed to have a visible impact on the nuclear suppression factor both at the RHIC and LHC.

The vibrant experimental programs on heavy-ion collisions pursued at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) have strongly suggested the existence of a hot and dense phase of nuclear matter, known as the quark-gluon plasma (QGP) [1,2,3,4,5]

Summary
The vibrant experimental programs on heavy-ion collisions pursued at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) have strongly suggested the existence of a hot and dense phase of nuclear matter, known as the quark-gluon plasma (QGP) [1,2,3,4,5]. Studies have shown that the physics of the Chromo-Weibel instability may have a significant role in understanding the properties of the QGP and its evolution in heavy-ion collision experiments [57,58,59,60] Such instabilities in the Yang-Mills field equations in the rapidly expanding QGP may lead to plasma turbulence as described in Ref. The current focus is to explore the heavy quark dynamics in the anisotropic (momentum) hot QCD medium while considering both the collisional and radiative processes of heavy quarks in the medium by incorporating the effects of anisotropy along the lines of Ref.
