摘要

我们对夸克-胶子等离子体中通过介质极化和胶子辐射造成的重夸克能量损失进行了比较研究。为此，我们研究了两种情况下的单位长度能量损失和阻力系数。为了更好地进行对比，我们还利用朗格文动力学获得了核修正因子。对比结果表明，在较低动量下，极化效应占主导地位。介质温度在比较中也起着重要作用。

Heavy quark energy loss through polarization and radiation in the hot QCD medium

We present a comparative study on the heavy quarks energy loss through medium polarization and gluon radiation in the quark-gluon plasma. To do so, we investigated the energy loss per unit length and drag coefficient for both cases. To have better contrast, we also obtained the nuclear modification factor employing Langevin dynamics. The comparison shows that the polarization effect dominates at lower momentum. The medium temperature also plays an important role in the comparison.
