全息光夸克喷注在RHIC和LHC通过射弦的猝灭

Holographic light quark jet quenching at RHIC and LHC via the shooting strings

Andrej Ficnar, Steven S. Gubser, Miklos Gyulassy

摘要:

提出了一个新的强耦合等离子体中轻夸克喷注猝灭的射弦全息模型,以克服以前的落弦全息方案与最近的LHC数据相矛盾的现象。这个模型是基于具有有限动量端点的弦,这些端点从视界附近开始,在接近边界时失去能量。应用该框架计算了RHIC和LHC上轻强子的核修正因子RAA,结果表明,该模型与最近的轻强子抑制数据相比,有很大的改进。高斯-博内二次曲率修正对AdS5几何形状的影响进一步提高了与数据的一致性。

英文摘要:

A new shooting string holographic model of jet quenching of light quarks in strongly coupled plasmas is presented to overcome the phenomenological incompatibilities of previous falling string holographic scenarios that emerged when confronted with the recent LHC data. This model is based on strings with finite momentum endpoints that start close to the horizon and lose energy as they approach the boundary. This framework is applied to compute the nuclear modification factor RAA of light hadrons at RHIC and LHC, showing that this model improves greatly the comparison with the recent light hadron suppression data. The effects of the Gauss-Bonnet quadratic curvature corrections to the AdS5 geometry further improve the agreement with the data.
