摘要:

中心性实验表明,在高能强子-核和核-核相互作用中发射的次级粒子的某些特性的行为的制度变化和饱和。这一现象具有批判性。简单的模型无法解释这种效应。我们认为,解释这一现象的机制可能是中间重子系统的形成和衰变。这样的系统可能是核子在压缩重子物质中渗透的结果。大渗流团的形成可能改变介质的性质,例如,它可能会导致透明度的改变。这可以用来得到一个信号的中间重子系统的形成。我们考虑两个信号来识别中间重子系统的形成:强相互作用物质的透明度的临界变化和轻核产生的增强与中心性的增加。

英文摘要:

The centrality experiments indicate regime change and saturation in the behavior of some characteristics of the secondary particles emitted in hadron-nuclear and nuclear-nuclear interactions at high energies. The phenomenon has a critical character. The simple models do not explain the effect. We suppose that the responsible mechanism to explain the phenomenon could be the formation and decay of the intermediate baryon systems. Such systems could be formed as a result of nucleon percolation in compressed baryonic matter. Formation of big percolation cluster may change the properties of the medium, e.g., it could lead to the changing its transparency. This could be used to get a signal of the intermediate baryonic system formation. We consider two signals to identify the formation of the intermediate baryon systems: the critical changing of transparency of the strongly interacting matter and the enhancement of light nuclei production with increase in centrality.
