论文摘要
高度多样性PP和P-PB碰撞的最新结果表明它们表现出类似于离子的行为。要了解这些意外现象的起源，事件形状如横向球体（$ s _ {\ rm 0}^{p _ {\ rm t} = 1} $）和相对横向活动分类器（$ r _ {\ rm {t}} $）可以用作强大的工具（$ r _ {\ rm _ {\ rm {t}） （扰动）粒子产生。在这里，显示了各种$ s _ {\ rm 0}^{p _ {\ rm t} = 1} $类别的PP碰撞类别的各种$ s _ {\ rm 0}^{pp collisionS $ \ sqrt {s} $ = 13 $ = 13 $ \ textrm {tev} $与Alice detector eal ealice dectector earted。具有带电的托运多重性的平均横向动量（$ \ langle p _ {\ rm t} \ rangle $）的演变，并确定粒子比为$ p _ {\ rm t} $的函数，用于不同的$ s _ {\ rm 0}^{p _ {此外，在$ \ sqrt {s _ {\ rm nn}} $ = 5.02 TEV中，PP，P-PB和PB-PB碰撞中带电的粒子产生的系统尺寸依赖性。出现了$ \ langle p _ {\ rm t} \ rangle $在不同拓扑区域作为$ r _ {\ rm {t}} $的函数的演变。最后，使用相同的方法，我们提出了小型碰撞系统中的喷气淬火行为的搜索。
Recent results for high multiplicity pp and p-Pb collisions have revealed that they exhibit heavy-ion-like behaviors. To understand the origin(s) of these unexpected phenomena, event shape observables such as transverse spherocity ($S_{\rm 0}^{p_{\rm T} = 1}$) and the relative transverse activity classifier ($R_{\rm{T}}$) can be exploited as a powerful tools to disentangle soft (non-perturbative) and hard (perturbative) particle production. Here, the production of light-flavor hadrons is shown for various $S_{\rm 0}^{p_{\rm T} = 1}$ classes in pp collisions at $\sqrt{s}$ = 13 $\textrm{TeV}$ measured with the ALICE detector at the LHC are presented. The evolution of average transverse momentum ($\langle p_{\rm T}\rangle$) with charged-particle multiplicity, and identified particle ratios as a function of $p_{\rm T}$ for different $S_{\rm 0}^{p_{\rm T} = 1}$ are also presented. In addition, the system size dependence of charged-particle production in pp, p-Pb, and Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV is presented. The evolution of $\langle p_{\rm T}\rangle$ in different topological regions as a function of $R_{\rm{T}}$ are presented. Finally, using the same approach, we present a search for jet quenching behavior in small collision systems.
