论文摘要
报道了由爱丽丝测量的质子质子质子（PP）碰撞中带电颗粒的假性密度的多重性依赖性。该分析依赖于在中期范围内测得的轨道段（$ |η| <1.5 $）。对于在伪时间间隔$ |η| <1 $（$ \ mathrm {inel} _ {> 0} $）中产生的至少一个带电粒子的非弹性事件提出了结果。带电颗粒的伪质密度的多样性依赖性是用中和正向快速估计器测量的，后者受到自相关的影响较小。还提出了与毕毕达8和EPOS LHC事件发生器的预测的详细比较。两种发电机都提供了数据的良好描述。
The multiplicity dependence of the pseudorapidity density of charged particles in proton-proton (pp) collisions at centre-of-mass energies $\sqrt{s}$ = 5.02, 7 and 13 TeV measured by ALICE is reported. The analysis relies on track segments measured in the midrapidity range ($|η| < 1.5$). Results are presented for inelastic events having at least one charged particle produced in the pseudorapidity interval $|η|<1$ ($\mathrm{INEL}_{>0}$). The multiplicity dependence of the pseudorapidy density of charged particles is measured with mid and forward rapidity multiplicity estimators, the latter being less affected by autocorrelations. A detailed comparison with predictions from the PYTHIA 8 and EPOS LHC event generators is also presented. Both generators provide a good description of the data.
