Martini数值模拟允许直接比较理论模型计算和来自ATLAS和CMS合作的双喷流不对称性的最新结果。本文模拟了在大型强子对撞机上铅-铅中心碰撞的整个演化过程中，部分子经历了辐射和碰撞过程。利用与Alice的带电粒子多重数数据相吻合的模拟所确定的流体动力学背景演化，并取{α}{亚S}{约}0.25-0.3的值，发现在热的强相互作用介质中，双喷流的不对称性与部分子能量损失是一致的。
The martini numerical simulation allows for direct comparison of theoretical model calculations and the latest results for dijet asymmetry from the ATLAS and CMS collaborations. In this paper, partons are simulated as undergoing radiative and collisional processes throughout the evolution of central lead-lead collisions at the Large Hadron Collider. Using hydrodynamical background evolution determined by a simulation which fits well with the data on charged particle multiplicities from ALICE and a value of {alpha}{sub s} {approx} 0.25-0.3, the dijet asymmetry is found to be consistent with partonic energy loss in a hot, strongly interacting medium.
