应用AdS/CFT对应关系,研究了在变形AdS背景下轻夸克在胶子凝聚作用下的射流猝灭现象。我们分别使用落管柱和射管柱进行分析。两种方法得出了一个一致的结论:胶子凝聚物的加入增加了能量损失。特别是,在限定相中,能量损失随着胶子凝聚物值的减小而减小,在高温下,能量损失几乎不受胶子凝聚物的修饰,这与射流淬火参数和阻力的研究结果一致。
Applying the AdS/CFT correspondence, we study the jet quenching of light quarks traversing in a deformed AdS background with backreaction due to the gluon condensate. We perform the analysis using the falling string and shooting string cases, respectively. It is found that the two methods lead to a unanimous conclusion: the inclusion of the gluon condensate enhances the energy loss. In particular, the energy loss decreases as the value of the gluon condensate decreases in the deconfined phase, and at high temperature, it is nearly not modified by the gluon condensate, in agreement with the findings of the jet quenching parameter and drag force.
