大小系统中的万有奇异性产生与尺度涨落

Universal strangeness production and size fluctuactions in small and large systems

P. Castorina, M. Floris, S. Plumari, H. Satz

摘要:

高多重数事例中奇异产生给出了核-核($AA$)、质子-核($pA$)和质子-质子($pp$)碰撞中横向尺寸涨落的指示。特别是奇异粒子强子化的行为在“小”($pp,pA$)和“大”($AA$)的初始配置的碰撞可以测试特定的粒子种类,为不同的中心和大波动的横向尺寸在$pA$和$pp$通过使用最近的ALICE数据。通过引入一个正比于横平面中初始部分子密度的动力学变量,奇异强子产生的普遍性得以显现。

英文摘要:

Strangeness production in high multiplicity events gives indications on the transverse size fluctuactions in nucleus-nucleus ($AA$), proton-nucleus ($pA$) and proton-proton ($pp$) collisions. In particular the behavior of strange particle hadronization in "small" ($pp,pA$) and "large" ($AA$) initial configurations of the collision can be tested for the specific particle species, for different centralities and for large fluctuations of the transverse size in $pA$ and $pp$ by using the recent ALICE data. A universality of strange hadron production emerges by introducing a dynamical variable proportional to the initial parton density in the transverse plane.
