论文摘要

已经观察到,随着事件带电的粒子多重性,相对于触发的奇怪和多震动黑质的产率显着增加。我们从实验数据中注意到,在非震撼力的哈德子(例如p/$π$)或具有相同奇怪内容的哈德子(例如$λ$/k $ _s^0 $)之间产生比率,显示出相似的增强。我们已经在PARTON模型(EPOS3)的范围内研究了这种行为,在LHC Energies的PP和P-PB碰撞中的多相传输(AMPT)模型。我们研究了不同鉴定的强子生产的产量和产量比的模型预测,这是带电粒子多重性的函数,并将其与已发表的爱丽丝结果进行了比较。发现AMPT和EPO的弦熔化版本在粒子产量比中建立增强。

It has been observed that the yields of strange and multi-strange hadrons relative to pion increase significantly with the event charged-particle multiplicity. We notice from experimental data that yield ratios between non-strange hadrons, like p/$π$ or hadrons of same strange content, like $Λ$/K$_s^0$, show similar enhancement. We have studied this behavior within the ambit of a parton model (EPOS3) and A Multi-Phase Transport (AMPT) model in pp and p-Pb collisions at LHC energies. We investigate model predictions of yields and yield ratios of different identified hadron productions as a function of charged-particle multiplicity and compare them with published ALICE results. The string melting versions of AMPT and EPOS are found to establish enhancements in the particle yield ratios.
