The observation of long range ridge-like structure in the near-side region of the two particle $\Delta\eta-\Delta\phi$ correlations as measured by LHC experiments in high multiplicity p$-$p collisions indicated towards the presence of collective effects which are similar to that observed in p$-$A(nucleon-nucleus) and A$-$A (nucleus-nucleus) collisions. The two particle correlation between the charged particles in $\Delta\eta-\Delta\phi$ for p$-$p collisions at $\sqrt{s}$ = 7 TeV and 13 TeV is studied using Pythia 8 event generator within the framework of final-state partonic color reconnection effects as well as the microscopic rope hadronization model. The rope hadronization relies on the formation of ropes due to overlapping of strings in high multiplicity events followed by string shoving. A near side ridge-like structure which is qualitatively similar to the observed ridge in data was observed for high-multiplicity events when the mechanism of rope hadronization (with shoving) was enabled.

在欧洲核子研究中心大型强子对撞机可用的能量下使用绳索强子化了解 p-p 碰撞中的长程近侧脊相关性

通过 LHC 实验在高多重 p$-$p 碰撞中测量的两个粒子近侧区域的长程脊状结构的观察结果表明存在集体效应类似于在 p$-$A（核子-核）和 A$-$A（核-核）碰撞中观察到的效应。使用 Pythia 8 事件发生器研究了 $\Delta\eta-\Delta\phi$ 中带电粒子在 $\sqrt{s}$ = 7 TeV 和 13 TeV 处发生 p$-$p 碰撞时的两个粒子相关性。最终状态分子颜色重联效应的框架以及微观绳索强子化模型。绳子强子化依赖于绳子的形成，这是由于在高多重事件中绳子的重叠，然后是绳子推。
