论文摘要
在这项研究中，Momentum-Kick模型用于了解LHC最近报告的Dihadron $δη$ - $Δφ$相关性的脊行为。踢台模型是基于带领喷气机队在接近领先喷气机的媒介中的动力踢的基础上。无论碰撞系统如何，模型中都可以自由地假设Partons移动的介质。这有助于我们以简单的方式将方法应用于PP碰撞等小型系统。同样，动量转移纯粹是运动学的，这为我们提供了一种很好的方法来分析山脊行为。这种方法在RHIC和LHC的CMS的高能重型离子碰撞中已经有几个结果。动量踢模型扩展到最近的脊，导致LHC与Atlas和CMS的高质量PP碰撞。在模型的结果中诊断出高多重PP碰撞中的中型属性。
In this study, the momentum-kick model is used to understand the ridge behaviours in dihadron $Δη$--$Δφ$ correlations recently reported by the LHC in high-multiplicity proton-proton (pp) collisions. The kick stand model is based on a momentum kick by leading jets to partons in the medium close to the leading jets. The medium where partons move freely is assumed in the model regardless of collision systems. This helps us apply the method to small systems like pp collisions in a simple way. Also, the momentum transfer is purely kinematic and this provides us a strong way to approach the ridge behaviour analytically. There are already several results with this approach in high-energy heavy-ion collisions from the STAR and PHENIX at RHIC and from the CMS at LHC. The momentum-kick model is extended to the recent ridge results in high-multiplicity pp collisions with the ATLAS and CMS at LHC. The medium property in high-multiplicity pp collisions is diagnosed with the result of the model.
