摘要：
稀有中微子过程的建模通常依赖于简单的近似或昂贵的探测器模拟。前者通常不足以应对具有复杂形态的相互作用，而后者对于唯象研究而言过于耗时。我们提出了SIREN（Sampling and Injection for Rare EveNts），这是一个用于中微子唯象研究和实验探索的新工具，它能够实现准确的相互作用和探测器几何建模，而无需承担详细探测器响应模拟的开销。SIREN能够处理稀有过程末态的注入及相关的权重计算，其速度满足唯象研究的需求，其细节程度也足以进行专门的实验探索。SIREN的可扩展设计使其能够支持广泛的实验设计和超标准模型中微子相互作用。用户只需指定所考虑的物理过程、探测器几何形状和初始中微子通量，即可在其选择的探测器中准确模拟模型。我们通过两个示例展示了SIREN的能力：(1) IceCube、DUNE和ATLAS中的标准模型$ν_μ$深度非弹性散射；以及(2) MiniBooNE、MINER$ν$A和CCM中的重中性轻子相互作用。同时还提供了多种探测器几何描述、相互作用截面和中微子通量，供用户立即开始使用。
英文摘要：
Modeling of rare neutrino processes often relies on either simple approximations or expensive detector simulations. The former is often not sufficient for interactions with complex morphologies, while the latter is too time-intensive for phenomenological studies. We present SIREN (Sampling and Injection for Rare EveNts), a new tool for neutrino phenomenology and experimental searches alike that enables accurate interaction and detector geometry modeling without the overhead of detailed detector response simulations. SIREN handles the injection of rare process final states and the associated weighting calculations with the speed needed for phenomenological investigations and the detail necessary for dedicated experimental searches. The extensible design of SIREN allows it to support a wide range of experimental designs and Beyond-Standard-Model neutrino interactions. Users need only specify the physical process, detector geometry, and initial neutrino flux under consideration before they can accurately simulate a model in their detector of choice. We demonstrate the capability of SIREN through two examples: (1) Standard Model $ν_μ$ deep inelastic scattering in IceCube, DUNE, and ATLAS; and (2) heavy neutral lepton interactions in MiniBooNE, MINER$ν$A, CCM. A variety of detector geometry descriptions, interaction cross sections, and neutrino fluxes are also provided for users to get started with immediately.
