软壁AdS/QCD模型中的轻夸克能量损失

Light quark energy loss in a soft-wall AdS/QCD model

Xiangrong Zhu, Zi-qiang Zhang

摘要:

研究了在背景夸克破坏共形不变性的全息QCD模型中轻夸克的能量损失。我们分别在落管柱和激发管柱内进行分析。结果表明,这两种方法得到了相同的结果:化学势和封闭尺度的存在会增加能量损失,这与前人关于阻力和射流淬熄参数的研究结果一致。

英文摘要:

We investigate the energy loss of light quarks in a holographic QCD model with conformal invariance broken by a background dilaton. We perform the analysis within falling string and shooting string, respectively. It turns out that the two methods give the same result: the presence of chemical potential and confining scale tends to enhance the energy loss, in accord with previous findings of drag force and jet quenching parameter.
