用Alice装置测量了TeV上pp碰撞中的两粒子方位角关联，探讨了在产生具有横向动量GeV/c的奇异介子(K)或重子()的条件下，喷注碎裂过程中的奇异性和多重性相关效应以及体态和硬态产物之间的过渡机制。对于大范围的触发(GeV/)和相关粒子(1GeV/)，对于最小偏置事件和作为事件多重数的函数，介子或超子与其他强子之间的方位角关联被呈现在中快度。比较了Kor()作为触发粒子和包含性强子(一个由介子主导的样本)的情况下的近侧和远侧峰值产额。此外，将测量结果与来自PYTHIA 8和EPOS LHC事件产生器的预测进行了比较。
Two-particle azimuthal correlations are measured with the ALICE apparatus in pp collisions atTeV to explore strangeness- and multiplicity-related effects in the fragmentation of jets and the transition regime between bulk and hard production, probed with the condition that a strange meson (K) or baryon () with transverse momentumGeV/c is produced. Azimuthal correlations between kaons orhyperons with other hadrons are presented at midrapidity for a broad range of the trigger (GeV/) and associated particle(1 GeV/), for minimum-bias events and as a function of the event multiplicity. The near- and away-side peak yields are compared for the case of either Kor() being the trigger particle with that of inclusive hadrons (a sample dominated by pions). In addition, the measurements are compared with predictions from PYTHIA 8 and EPOS LHC event generators.
