重离子碰撞中喷流的蒙特卡罗模拟

Monte-Carlo simulation of jets in heavy-ion collisions

Clint Young, Sangyong Jeon, Charles Gale, Bjoern Schenke

摘要:

我们提出了蒙特卡罗模拟的喷流演化的铅-铅碰撞在大型强子对撞机(LHC)在欧洲核子研究中心的重点是双喷流不对称测量的ATLAS和CMS合作。在模拟中,硬部分子与流体动力学背景介质相互作用,经历辐射和碰撞过程。模拟很好地描述了测得的双喷射不对称性,因此与热的强相互作用介质中的部分子能量损失是一致的。

英文摘要:

We present Monte-Carlo simulations of jet evolution in lead-lead collisions at the Large Hadron Collider (LHC) at CERN focusing on the dijet asymmetry measured by the ATLAS and CMS collaborations. In the simulation, hard partons are interacting with the hydrodynamical background medium, undergoing radiative and collisional processes. The measured dijet asymmetry is well described by the simulation and is hence consistent with partonic energy loss in a hot, strongly-interacting medium.
