论文摘要
为了研究以$Δη$ = 0.1、0.2和0.5的狭窄伪装窗口产生的高局部密度的电荷颗粒密度的事件，对大型强子对撞机（LHC）的Proton-Proton（$ PP $）碰撞进行了模拟。 $ pp $碰撞是在$ \ sqrt {s} = 2.36 $，$ 7 $，$ 8 $和$ 13 $ tev的中心生成的。我们还研究了使用不同的伪型窗口，研究了所有事件的最大带电粒子密度的平均值与事件多重性的平均值。这项研究为在未来使用LHC数据进行异常高密度多样性波动时预期的多粒子生产背景做好了准备。
Proton-Proton ($pp$) collisions at the Large Hadron Collider (LHC) are simulated in order to study events with a high local density of charged particles produced in narrow pseudorapidty windows of $Δη$ = 0.1, 0.2, and 0.5. The $pp$ collisions are generated at center of mass energies of $\sqrt{s} = 2.36$, $7$, $8$, and $13$ TeV, i.e. the energies at which the LHC has operated so far, using PYTHIA and HERWIG event generators. We have also studied the average of the maximum charged-particle density versus the event multiplicity for all events, using the different pseudorapidity windows. This study prepares for the multi-particle production background expected in a future search for anomalous high-density multiplicity fluctuations using the LHC data.
