报告摘要：
Collisional energy loss of heavy partons (charm and bottom quarks) has been determined within the framework of effective kinetic theory implying Bhatnagar-Gross-Krook (BGK) collisional kernel. Hot QCD medium effects have been incorporated while employing a quasi-particle description of the hot QCD medium in terms of effective gluons, quarks and antiquarks with their respective temperature-dependent effective fugacities. Then the momentum dependence of the energy loss for the charm and bottom quark has been investigated. It is observed that with the increase in momentum of the heavy quark, the energy loss increases sharply for the smaller values and later reaches a saturation. Further, as compared to the charm quark, the bottom quark loses less energy at a particular momentum and collisional frequency. The energy loss is seen to increase with increasing collisional frequency. The medium interaction effects are found to suppress the energy loss of both charm and bottom quarks. Further, as an expansion to this work, a few results on the effect of small but finite chemical potential has also been presented.
