摘要:

我们分析了强子-核相互作用和核-核相互作用的不同特征随中心性的变化,以获得中间重子系统形成的信号。我们观察到,数据表明政权的变化和饱和。在低能反应中,慢粒子的角分布呈现出一定的结构。我们认为这种结构可能与渗流团簇的形成和衰变有关。随着碰撞核质量的增加,这种结构开始变弱,最终几乎消失。这表明次级核间相互作用的数量随着碰撞核质量的增加而增加。后者可能是任何中间形成物以及团簇解体的原因,这降低了它们对发射粒子的角分布的影响。

英文摘要:

We have analyzed the behavior of different characteristics of hadron-nuclear and nuclear-nuclear interactions as a function of centrality to get a signal on the formation of intermediate baryon systems. We observed that the data demonstrate the regime change and saturation. The angular distributions of slow particles exhibit some structure in the above mentioned reactions at low energy. We believe that the structure could be connected with the formation and decay of the percolation cluster. With increasing the mass of colliding nuclei, the structure starts to become weak and almost disappears ultimately. This shows that the number of secondary internuclear interactions increases with increasing the mass of the colliding nuclei. The latter could be a reason of the disintegration of any intermediate formations as well as clusters, which decrease their influence on the angular distribution of the emitted particles.
