标题： A test of strangeness quantum number conservation in proton-proton collisions

摘要： 该研究深入探讨了在LHC的质子-质子碰撞中（多）奇异强子的产生。提出了新的观测量，以区分基于热化QGP相与真空相之间核心-晕分离的EPOS4模型，以及基于Lund弦之间微观相互作用并局部守恒奇异性的PYTHIA8.3模型。显示$\phi$介子与（多）奇异强子之间的关联是区分这两种模型的优秀判据。 显示英文摘要

摘要： The study delves into the production of (multi-)strange hadrons in proton-proton collisions at LHC. Novel observables are proposed to distinguish between EPOS4, based on core-corona separation between a thermalised QGP phase and a vacuum phase with global strangeness conservation, and PYTHIA8.3, based on microscopic interactions between Lund strings that conserve strangeness locally. Correlations between a $\phi$ meson and (multi-)strange hadrons are shown to be an excellent discriminator between the two types of models.
