激波处理:新型AdS/CFT几何中的重夸克能量损失

Shock Treatment: Heavy Quark Energy Loss in a Novel AdS/CFT Geometry

W. A. Horowitz

摘要:

我们首先注意到传统的pQCD技术应用于高pT重离子物理的失败,并建议检查的魅力,底部核修改因素的双比一般区分这些弱耦合的想法和强耦合的AdS/CFT的想法。为了获得信心,在使用AdS/CFT(并增加伪造它和/或pQCD的可能性),我们将其应用扩展到重夸克能量损失的热介质和非热介质通过计算弦阻力的冲击度规。

英文摘要:

We first note the failures of traditional pQCD techniques as applied to high-pT heavy ion physics and the suggestion of examining the double ratio of charm to bottom nuclear modification factors to generically distinguish between these weak coupling ideas and the strong coupling ideas of AdS/CFT. In order to gain confidence in the use of AdS/CFT (and to increase the likelihood of falsifying it and/or pQCD) we extend its application to heavy quark energy loss in both thermal and nonthermal media by calculating the string drag in a shock metric.
