摘要:

在 Yang-Mills 理论中应用的 Gribov-Zwanziger 处方被证明是改进该理论红外动力学的一种有效方法。我们研究高能测试部分子在有限温度下穿过 Grivov 等离子体时所经历的碰撞能量损失。为此,我们采用半经典方法,在考虑部分子能量损失的同时,计入其在介质中运动所引起的极化效应带来的反作用。介质的极化张量是在考虑 Gribov-Zwanziger 方法的非微扰重求和框架内估计的。由 Gribov 参数的存在所导致的胶子和鬼圈修正,在我们的估计中起着关键作用。我们观察到,非微扰相互作用对部分子能量损失具有相当大的影响。此外,我们还在相对论重离子碰撞的背景下讨论了研究结果的意义。

英文摘要:

The Gribov-Zwanziger prescription applied within Yang-Mills theory is demonstrated to be an efficient method for refining the theory's infrared dynamics. We study the collisional energy loss experienced by a high-energetic test parton as it traverses through the Grivov plasma at finite temperature. To achieve this, we employ a semi-classical approach that considers the parton's energy loss while accounting for the back-reaction induced by the polarization effects due to its motion in the medium. The polarization tensor of the medium is estimated within a non-perturbative resummation considering the Gribov-Zwanziger approach. The modification of the gluon and ghost loops due to the presence of the Gribov parameter plays a vital role in our estimation. We observe that the non-perturbative interactions have a sizable effect on the parton energy loss. Further, we discuss the implications of our findings in the context of relativistic heavy-ion collisions.
