利用最近发表的模型[gossip and Aichelin， Phys]。基于具有运行耦合常数的微扰QCD (pQCD)，我们详细研究了重夸克与等离子体粒子之间的相互作用。物理学报，78,014904(2008)]。我们讨论了同时产生的c和c夸克之间的相关性，研究了如何在实验中选择中心碰撞，预测可观察到的相关性，并将我们的模型扩展到大型强子对撞机（LHC）的能量域。最后，我们将该模型的预测结果与其他方法如反德西特/共形场理论（AdS/CFT）进行了比较。
Using the recently published model [Gossiaux and Aichelin, Phys. Rev. C 78, 014904 (2008)] for the collisional energy loss of heavy quarks in a quark gluon plasma (QGP), based on perturbative QCD (pQCD) with a running coupling constant, we study the interaction between heavy quarks and plasma particles in detail. We discuss correlations between the simultaneously produced c and c quarks, study how central collisions can be experimentally selected, predict observable correlations, and extend our model to the energy domain of the Large Hadron Collider (LHC). We finally compare the predictions of our model with that of other approaches such as anti-de Sitter/conformal field theory (AdS/CFT)
