The transverse momentum (\(p_{T}\)) distribution of strange hadrons (\(K_{S}^{0}\) and \(\varLambda \)) and multi-strange hadrons( \(\varXi \) and \(\varOmega \)) measured in p–p, p–Pb, and Pb–Pb collisions at LHC energies has been studied for different multiplicity classes using Tsallis–Weibull (or q-Weibull) formalism. The distribution describes the measured \(p_{T}\) spectra for all multiplicity (or centrality) classes. The multiplicity dependence of the extracted parameters were studied for the mentioned collision systems. The \(\lambda \) parameter was observed to increase systematically with the collision multiplicity and follows a mass hierarchy for all collision systems. This characteristic feature indicates that \(\lambda \) can be associated to the strength of collectivity in heavy ion collisions. It can also be related to strength of dynamic effects such as multi-partonic interactions and color reconnections which mimic collectivity in smaller systems. The non-extensive q parameter is found to be greater than one for all the particles suggesting that the strange particles are emitted from a source which is not fully equilibrated.

使用Tsallis-Weibull形式论的LHC能量在p–p，p–Pb和Pb–Pb碰撞中，奇异和多奇异强子的多重依赖性

奇怪的强子（\（K_ {S} ^ {0} \）和\（\ varLambda \））和多奇强子（\（\ varXi \）的横向动量（\（p_ {T} \））分布使用Tsallis-Weibull（或q-Weibull）形式论研究了LHC能量在p–p，p–Pb和Pb–Pb碰撞中测得的\和\（\ varOmega \））。该分布描述了所有多重性（或中心性）类别的测量\（p_ {T} \）光谱。对于提到的碰撞系统，研究了提取参数的多重依赖性。的\（\拉姆达\）观察到参数随着碰撞多重性而系统地增加，并且遵循所有碰撞系统的质量等级。此特征表明\（\ lambda \）可以与重离子碰撞中的集合体强度相关联。它也可能与动态效果的强度有关，例如在较小的系统中模拟多集合体的多粒子交互作用和颜色重新连接。发现所有粒子的非扩展q参数均大于1，这表明奇怪的粒子是从未完全平衡的源发出的。
