"Table 1" of "Particle production as a function of charged-particle flattenicity in pp collisions at $\sqrt{s}$ = 13 TeV"

Transverse momentum spectrum of $\pi^{+} + \pi^{-}$ measured at midrapidity ($|y|<0.5$) in INEL>0 pp collisions at $\sqrt{s}$ = 13 TeV for different flattenicity event classes selected with the V0M estimator at forward rapidity (top figure, upper panel)

在√s=13 TeV的INEL>0质子-质子（pp）碰撞中，利用前向快度处的V0M估计器选择不同平坦度事件类别后，于中快度区（|y|<0.5）测量得到的π⁺+π⁻横向动量谱（上图，上半部分）
