AI 中文摘要
天体物理中微子是超高能宇宙射线（UHECRs）源中光强子相互作用的明确标识。由于皮埃尔·奥格天文台已表明，UHECRs在地球上表现出比质子更重的成分，我们预期这些重初级粒子在其起源的致密源环境中因光致蜕变而发生核级联。在本文中，我们将推导包括那些源自经历光强子相互作用的原子核的中微子谱。这将在对伽马射线暴发射区进行建模的背景下进行探讨。光强子相互作用将使用新的宇宙射线随机相互作用传播（CRISP）框架进行建模，该框架采用解析方法来计算UHECR相互作用的潜在概率描述。
英文摘要
Astrophysical neutrinos are a clear identifier of photohadronic interactions in sources of Ultra-High-Energy Cosmic Rays (UHECRs). As the Pierre Auger Observatory has shown that UHECRs exhibit a composition heavier than protons at Earth, we expect that these heavy primaries undergo nuclear cascades due to photodisintegration in the dense source environments from which they originate. In this contribution, we will derive the neutrino spectra including those originating from nuclei undergoing photohadronic interactions. This will be explored in the context of modeling the emission region of a gamma-ray burst. Photohadronic interactions will be modeled using the new framework for Cosmic Ray Stochastic Interactions for Propagation (CRISP), which employs an analytic approach to compute the underlying probabilistic description of UHECR interactions.
