The remarkable agreement between observations of the primordial light element abundances and the corresponding theoretical predictions within the standard cosmological history provides a powerful method to constrain physics beyond the standard model of particle physics (BSM). For a given BSM model these primordial element abundances are generally determined by (i) Big Bang Nucleosynthesis and (ii) possible subsequent disintegration processes. The latter potentially change the abundances due to late-time high-energy injections which may be present in these scenarios. While there are a number of public codes for the first part, no such code is currently available for the second. Here we close this gap and present ACROPOLIS, A generiC fRamework fOr Photodisintegration Of LIght elementS. The widely discussed cases of decays as well as annihilations can be run without prior coding knowledge within example programs. Furthermore, due to its modular structure, can easily be extended also to other scenarios.

雅典卫城:轻元素光分解的通用框架

对原始轻元素丰度的观察与标准宇宙学历史中相应的理论预测之间的显着一致性提供了一种强有力的方法来约束超出粒子物理学标准模型 (BSM) 的物理学。对于给定的 BSM 模型,这些原始元素丰度通常由(i) 大爆炸核合成(ii) 可能的后续分解过程决定. 后者可能会由于这些场景中可能存在的晚期高能注入而改变丰度。虽然第一部分有许多公共代码,但第二部分目前没有这样的代码。在这里,我们缩小了这一差距并提出了雅典卫城,这是一种用于光元素光分解的通用框架。广泛讨论的衰变和湮灭案例可以在没有示例程序中的先验编码知识的情况下运行。此外,由于其模块化结构,也可以轻松扩展到其他场景。有关本手册的最新版本,请访问位于 https://github.com/skumblex/acropolis 的 GitHub 存储库。
