论文摘要
Quarkonia代表了理解倍度相互作用（MPI）在小型系统（即PP和P-A碰撞）中的作用的出色工具。可以直接查看Quarkonium相关的产生，或通过研究Quarkonium生产的多重性依赖性来直接进行Quarkonia探测MPI。在这些程序中，讨论了关于直接和间接MPI探针的爱丽丝实验的结果。分别讨论了Charmon产生的产量，分别讨论了\ sqrt {s} = 13 tev和\ sqrt {s_ {nn} = 8.16 TEV的PP和P-PB碰撞中带电的粒子多重性的函数。此外，报道了Charmon自称为激发与地面比率的相应测量值是带电粒子多重性的函数。提出了\ sqrt {s} = 13 tev tev tev tev的PP碰撞中的双J/ψ产量的新测量。最后，讨论了\ sqrt {s} = 13 tev中PP碰撞中底部生产的多重性依赖性。报告了与可用理论计算的比较。
Quarkonia represent excellent tools for understanding the role of multiparton interactions (MPI) in small systems, i.e., pp and p-A collisions. Probing MPI with quarkonia can be done directly by looking at quarkonium associated production, or indirectly by studying the multiplicity dependence of quarkonium production. In these proceedings, the results from the ALICE experiment on direct and indirect MPI probes are discussed. The self-normalized yields of charmonium production as a function of the charged-particle multiplicity in pp and p--Pb collisions at \sqrt{s} = 13 TeV and \sqrt{s_{NN} = 8.16 TeV, respectively, are discussed. Additionally, the corresponding measurements of the charmonium self-normalized excited-to-ground state ratio as a function of the charged-particle multiplicity are reported. The new measurement of the double J/ψproduction at forward rapidity in pp collisions at \sqrt{s} = 13 TeV TeV is presented. Finally, the multiplicity dependence of the bottomonium production in pp collisions at \sqrt{s} = 13 TeV is discussed. The comparison to the available theoretical calculations is reported.
