$η$和$ω$介子作为核内级联模型INCL中的新自由度
$η$ and $ω$ mesons as new degrees of freedom in the intranuclear cascade model INCL
摘要：
核内级联模型INCL（列日核内级联）现在能够模拟由能量高达约15 GeV的射弹引起的空间反应。这是由于在NN、$Δ$ N和$π$ N相互作用中实现了多介子发射而成为可能。用核子或π介子引起的核反应得到的结果使模型具有可信度。下一步将是加入奇怪的粒子，$Λ$，$Σ$和Kaons，不仅为了改进高能模型，而且为了扩展INCL的能力，研究超核物理。在这两个版本的代码之间，在INCL中处理$η$和$ω$介子的可能性已经执行，这是本文的主题。这些介子的产额随着能量的增加而增加，在更高的能量下测试它们的作用是有趣的。更具体地说，对$η$稀有衰变的研究得益于对其产生的精确模拟。这是他们实施的两个原因。讨论了模型中的基本反应截面等成分，并与实验数据进行了比较，以检验这些粒子产生的可靠性。
英文摘要：
The intranuclear cascade model INCL (Liège Intranuclear Cascade) is now able to simulate spallation reactions induced by projectiles with energies up to roughly 15 GeV. This was made possible thanks to the implementation of multipion emission in the NN, $Δ$N and $π$N interactions. The results obtained with reactions on nuclei induced by nucleons or pions gave confidence in the model. A next step will be the addition of the strange particles, $Λ$, $Σ$ and Kaons, in order to not only refine the high-energy modeling, but also to extend the capabilities of INCL, as studying hypernucleus physics. Between those two versions of the code, the possibility to treat the $η$ and $ω$ mesons in INCL has been performed and this is the topic of this paper. Production yields of these mesons increase with energy and it is interesting to test their roles at higher energies. More specifically, studies of $η$ rare decays benefit from accurate simulations of its production. These are the two reasons for their implementation. Ingredients of the model, like elementary reaction cross sections, are discussed and comparisons with experimental data are carried out to test the reliability of those particle productions.
