Energy Loss of a Heavy Quark in a Collisional Quark-Gluon Plasma
Mingda Cai, Yun Guo
We extend our previous work on the energy loss of a heavy fermion in a QED plasma to the Quark-Gluon plasma, using the same Bhatnagar-Gross-Krook collisional kernel. The calculatio…

Suppression of the jet quenching parameter near the critical temperature
Haibo Ren, Qianqian Du, Yun Guo
In this work, we study the jet quenching parameter by using a background field effective theory. Particular attention is paid to its behavior near the critical temperatu…

Influence of a nontrivial Polyakov loop on the quarkonium states
Wenqiang Liu, Lihua Dong, Yun Guo
Using a hybrid approach based on a phenomenological heavy-quark potential model and the background field effective theory, we assess the influence of a nontrivial Polyakov loop on…
