Query: Energy loss of heavy quarks in the isotropic collisional hot QCD medium   Collisional energy loss of heavy partons (charm and bottom quarks) has been
determined within the framework of semi-classical transport theory implying
Bhatnagar-Gross-Krook (BGK) collisional kernel. Hot QCD medium effects have
been incorporated while employing a quasi-particle description of the medium in
terms of effective gluons, quarks and antiquarks with respective temperature
dependent effective fugacities. The momentum dependence of the energy loss for
charm and bottom quark has been investigated. It is observed that with the
increase in momentum of the heavy quarks, the loss increases sharply for the
smaller values and reaches a saturation later. Further, as compared to the
charm quark, bottom quark losses less energy at a particular momentum and
collisional frequency. The energy loss is seen to increase with increasing
collisional frequency. We also provide a comparative study of the results
obtained using BGK-kernel than those using relaxation time approximation
(RTA)-kernel and found them consistent with each other. The medium effects in
all the situations are seen to play quite significant role.
