论文摘要
本文是{\ color {blue} ur。由于在有限的巴里昂密度和中等温度下,即将到来的实验设施(例如抗蛋白和离子研究(FAIR)和基于核激素的离子碰撞器设施(NICA),因此可以探索QCD相图的探索,因此纳入有限的化学电位对于研究热QCD/QGP培养基至关重要。因此,目的是开发一种形式主义,以研究具有较小但有限的夸克化学势的相互作用的碰撞热QCD培养基中移动的重夸克的能量损失。为此,已经采用了扩展有效的散型准粒子模型\ cite {chandra_quasi1,chandra_quasi2,mitra:2017sjo},同时考虑了使用bhatnagar-gross-krook(bgk)(bgk)的有效动力学理论方法。最后,在碰撞频率和化学潜力的不同值下研究了能量损失对魅力和底部夸克的动量依赖性。据观察,与魅力夸克相比,底部夸克在特定动量,碰撞频率和化学潜力下失去了较少的能量。同样,由于化学势的增加,能量损失会减少。
The present article is the followup of {\color{blue} Eur.\ Phys.\ J.\ C {\bf 79}, 761 (2019)}, where we have studied the energy-loss of the heavy quarks traversing through the isotropic collisional hot QCD medium. Since, the exploration of QCD phase diagram is possible with the upcoming experimental facilities such as Anti-proton and Ion Research (FAIR) and Nuclotron-based Ion Collider fAcility (NICA), at finite baryon density and moderate temperature, the inclusion of finite chemical potential is essential to study the hot QCD/QGP medium. Therefore, the aim is to develop a formalism to study the energy-loss of heavy quarks moving in the interacting collisional hot QCD medium having small but a finite quark chemical potential. To do so, the extended effective fugacity quasi-particle model has been employed \cite{chandra_quasi1, chandra_quasi2, Mitra:2017sjo} while considering the effective kinetic theory approach using the Bhatnagar-Gross-Krook (BGK) collisional kernel. Finally, the momentum dependence of the energy-loss for the charm and bottom quark has been investigated at different values of collisions frequency and chemical potential. It is observed that as compared to charm quark, bottom quark loses less energy at a particular momentum, collisional frequency and chemical potential. Also, the energy-loss is seen to decrease with increasing chemical potential.
