论文摘要
了解重型离子碰撞中产生的物质的特性的重要观察是其陌生内容。最近的实验结果表明,在半个中央碰撞中,$λ$和$ \barλ$全球极化显示出在低能量下增加的差异。已经使用模型描述了这种行为,其中这些颗粒可以从碰撞区域的两个不同密度区域产生:核心和电晕,QGP过程分别和P + P(如反应)主要在起作用。使用这个想法,极化可能会受到来自任何一个区域的这些颗粒的相对丰度的影响。在这项工作中,我们展示了如何在MPD实验中测试该模型。
An important observable to understand the properties of the matter produced in heavy-ion collisions is its strangeness content. Recent experimental results show that in semi-central collisions, the $Λ$ and $\barΛ$ global polarization show differences that increase at low energies. This behaviour has been described using a model where these particles may be produced from two distinct density zones in the collision region: the core and the corona where QGP processes and p + p like reactions, respectively, are mainly at work. Using this idea, the polarization can be influenced by the relative abundance of these particles coming from either regions. In this work we show how to test this model in the MPD experiment.
