论文摘要
在$ \ sqrt {s} $ = 13 tev和p-pb碰撞$ \ sqrt {s _ {s _ {\ mathrm {nn}} $ = 8.16 tev中，在$ \ sqrt {s _ sqrt collisions中，$ \ sqrt {s} $ = 13 tev和p-pb碰撞在$ \ sqrt {s} $ = 13 tev和p-pb碰撞时，自动归一化的$ψ（2s）$的收益率是$ \ sqrt {s} $ = 13 tev和p-pb碰撞的函数的函数。该测量代表了了解倍度相互作用的作用及其对小系统中charmonium生产的影响的主要工具之一，即PP和PA碰撞。对于PP和P-PB碰撞，还列出了$ψ（2s）$ - OVER-J/$ψ$作为带电粒子多重性的函数的比率。报告了与理论计算的比较。
The self-normalised $ψ(2S)$ yields as a function of charged-particle multiplicity in pp collisions at $\sqrt{s}$ = 13 TeV and p--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$= 8.16 TeV, using the ALICE detector at the CERN LHC, are reported in these proceedings. This measurement represents one of the main tools to understand the role of multiparton interactions and their influence on charmonium production in small systems, i.e pp and pA collisions. The ratio of $ψ(2S)$-over-J/$ψ$ as a function of charged-particle multiplicity is also presented for both pp and p--Pb collisions. The comparison to theoretical calculations is reported.
