摘要:

详细介绍了列日核内级联模型(INCL++6)的新版本的能力。这个新版本的INCL能够处理奇异粒子,如K介子和$Λ$粒子,以及相关的反应,也允许扩展核子-核子碰撞高达约$15-20$ GeV的入射能量。与以前的版本相比,可以研究新的可观测量,例如,K介子、超子和超核产生的截面(使用适当的去激发代码)以及K介子诱导的自旋反应的各个方面。本文的主要目的是介绍新的INCL版本的具体成分及其新功能,特别是新的方差减少计划。我们还比较了一些说明性的奇异性生产的情况下,使用这个版本的INCL与实验数据计算。

英文摘要:

The capabilities of the new version of the Liège Intra-Nuclear Cascade model (INCL++6) are presented in detail. This new version INCL is able to handle strange particles, such as kaons and the $Λ$ particle, and the associated reactions and also allows extending nucleon-nucleon collisions up to about $15-20$ GeV incident energy. Compared to the previous version, new observables can be studied, e.g., kaon, hyperon, and hypernuclei production cross sections (with the use of a suitable de-excitation code) as well as aspects of kaon-induced spallation reactions. The main purpose of this paper is to present the specific ingredients of the new INCL version and its new features, notably the new variance reduction scheme. We also compare for some illustrative strangeness production cases calculated using this version of INCL with experimental data.
