夸克物质09上的喷流介质相互作用

Jet Medium interactions at Quark Matter 09

Abhijit Majumder

摘要:

在重离子碰撞中,高横动量$p_{T}$强子产额的抑制,被称为“喷流淬灭”,现已发展成为一门综合性的科学。喷流现在被用来探测其传播所通过的稠密介质的各种性质。主要的理论改进包括在3-D流体动力学介质中的喷流修正,第一套介质中的蒙特卡罗实现,微扰QCD中的多强子观测量和能量流的理解,以及改进的AdS/CFT描述的能量损失。在实验方面,高统计数据允许对各种理论模型和近似值进行第一次判别检验,而完整喷注重建的新测量对理论提出了挑战。

英文摘要:

The suppression of the yield of high transverse momentum $p_{T}$ hadrons in heavy-ion collisions, referred to as "jet-quenching", has now developed into a comprehensive science. Jets are now used as probes of a variety of properties of the dense medium through which they propagate. Major theoretical improvements include jet modification in a 3-D fluid dynamical medium, the first set of in-medium Monte-Carlo implementations, an understanding of multi-hadron observables and energy flow within perturbative QCD, along with improvements in the AdS/CFT description of energy loss. On the experimental side, high statistics data are allowing for the first discriminatory test of various theoretical models and approximations while the new measurements of full jet reconstruction pose a challenge to theory.
