"Figure 6.1" of "Measurements of differential two-particle number and transverse momentum correlation functions in pp collisions at $\sqrt{\textit{s}}$ = 13 TeV"

Width of $R_2^{\rm CI}(\Delta\eta)$ and $P_2^{\rm CI}(\Delta\eta)$ correlation functions along $\Delta\eta$ measured within $|\Delta\varphi| < \pi$ in pp collisions and compared with results from $p-Pb$ and $Pb-Pb$ collisions as a function of $\langle \mathrm{d}N_\mathrm{ch}/\mathrm{d}\eta \rangle_{|\eta|<0.5}$.

在方位角差绝对值$|Deltavarphi|<pi$的约束下，于质子-质子（pp）碰撞中测得的$R_2^{
m CI}(Deltaeta)$与$P_2^{
m CI}(Deltaeta)$关联函数沿赝快度差$Deltaeta$的分布宽度，以赝快度区间$|eta|<0.5$内的平均带电粒子多重数密度$langle mathrm{d}N_{
m ch}/mathrm{d}eta
angle_{|eta|<0.5}$为自变量，与质子-铅（p-Pb）和铅-铅（Pb-Pb）碰撞的对应结果进行了对比。
