论文摘要
超新星散发出大的中微子通量,可以通过地球上的探测器检测到。未来的吨尺度探测器将对几个中微子相互作用通道敏感,如果在银河系中出现超新星,预计会有数千个事件。尽管存在大量可用的超新星模型,但数量有限的工具来研究超新星中微子的相互作用速率。 Estrellanueva是一种开源软件,可使用具有典型组成的目标材料来计算检测器中超新星中微子的预期速率,并且可以轻松添加其他组合物。该软件考虑了超新星通过绝热Mikheyev--smirnov-Wolfenstein效应的中微子的风味转化,以及通过多个通道在探测器中的相互作用。大多数相互作用的横截面已通过分析实现,例如中微子电子和中微子 - 普罗希望的弹性散射,反β衰变以及相干弹性中微子核核散射。该软件通过计算通力和事件速率来简化理论与观察之间的任何比较,从而提供了超新星模拟与检测器中预期事件之间的联系。它提供了一个简单而独立的工具,可以探索许多物理场景,为添加分析横截面并定义任何目标材料提供了一种选项。
Supernovae emit large fluxes of neutrinos which can be detected by detectors on Earth. Future tonne-scale detectors will be sensitive to several neutrino interaction channels, with thousands of events expected if a supernova emerges in the galaxy neighborhood. There is a limited number of tools to study the interaction rates of supernova neutrinos, although a plethora of available supernova models exists. EstrellaNueva is an open-source software to calculate expected rates of supernova neutrinos in detectors using target materials with typical compositions, and additional compositions can be easily added. This software considers the flavor transformation of neutrinos in the supernova through the adiabatic Mikheyev--Smirnov--Wolfenstein effect, and their interaction in detectors through several channels. Most of the interaction cross sections have been analytically implemented, such as neutrino-electron and neutrino-proton elastic scattering, inverse beta decay, and coherent elastic neutrino-nucleus scattering. This software provides a link between supernova simulations and the expected events in detectors by calculating fluences and event rates to ease any comparison between theory and observation. It provides a simple and standalone tool to explore many physics scenarios offering an option to add analytical cross sections and define any target material.
