论文摘要
重风味（HF）夸克，即魅力和美女，是通过硬散射过程在超相关碰撞的早期阶段产生的。重型风味与带电粒子多样性的函数的测量不仅提供了有关生产机制如何受到事件活动影响的信息，而且还可以被视为测试多个Parton相互作用的作用的工具。此外，带电的粒子多重性研究对于参考测量，调整理论模型并提供有关事件全球特征的信息至关重要。在爱丽丝（Alice）中，在中央速度速度和电子衰减通道中，带电的粒子多重性和重型流动性产生，而HF-Decay Muons和$ \ rm J/ψ\ righarrowμ^{+}+}μ^{ - } $在远期快速速度时测量。在这项贡献中，将在相对$ \ rm j/ψ$，平均D-Meson和HF强体衰减产量的瘦素上呈现结果，这是质子 - 蛋白（PP）碰撞中带电的粒子多重性的函数，$ \ sqrt {s} $ = 5.02、7、7、8和13 tev。这些结果也将与理论模型计算进行比较。
Heavy-flavour (HF) quarks, i.e. charm and beauty, are produced in the early stages of ultra-relativistic collisions via hard scattering processes. The measurement of heavy flavour as a function of charged-particle multiplicity not only provides information on how the production mechanisms are influenced by the event activity, but can also be considered as a tool to test the role of multiple parton interactions. Furthermore, charged-particle multiplicity studies are essential for reference measurements, to tune theoretical models and to provide information on the global characteristics of events. In ALICE, charged-particle multiplicity and heavy-flavour production in the hadronic and electronic decay channels are measured at central rapidity while HF-decay muons and $\rm J/ψ\rightarrow μ^{+}μ^{-}$ are measured at forward rapidity. In this contribution, results will be presented on relative $\rm J/ψ$, average D-mesons and leptons from HF hadron decay yields as a function of charged-particle multiplicity in proton-proton (pp) collisions at $\sqrt{s}$ = 5.02, 7, 8 and 13 TeV. These results will also be compared to theoretical model calculations.
