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 confining scale and chemical potential tends to enhance the energy loss, in accord with previous findings of drag force and jet quenching parameter.

软壁AdS / QCD模型中的轻夸克能量损失

我们研究了全息QCD模型中夸克的能量损失，其保形不变性被背景dilaton破坏了。我们分别在落弦和射弦中进行分析。事实证明，这两种方法得出的结果相同：与先前的阻力和射流淬火参数的发现相一致，限制尺度和化学势的存在往往会增加能量损失。
