论文摘要
与巨大玻色子的非标准中微子相互作用可以在核心 - 偏曲超新星(SNE)的核心中产生玻色子。从SN芯中排出玻色子后,它们随后的中微子腐烂可以改变SN中微子通量。我们显示了从超级kamiokande(SK)和Hyper-kamiokande(HK)中的下一个银河SN的未来观察结果,可以探测浅玻色孔的味道非标准中微子偶联,从而改善了SN 1987a中微子从几个大量级别爆发的先前限制。我们还讨论了从过去的SNE弥漫性中微子的未来观察结果中的风味 - 宇宙非标准中微子相互作用的灵敏度,称为弥漫性超新星中微子背景(DSNB)。根据我们的分析,对HK,Juno和Dune实验中DSNB的观察可以探究此类耦合的$ \ sim 2 $,超出了SN 1987a约束。但是,我们的结果还遭受了关于DSNB的精确估计的巨大不确定性。
Non-standard neutrino interactions with a massive boson can produce the bosons in the core of core-collapse supernovae (SNe). After the emission of the bosons from the SN core, their subsequent decays into neutrinos can modify the SN neutrino flux. We show future observations of neutrinos from a next galactic SN in Super-Kamiokande (SK) and Hyper-Kamiokande (HK) can probe flavor-universal non-standard neutrino couplings to a light boson, improving the previous limit from the SN 1987A neutrino burst by several orders of magnitude. We also discuss sensitivity of the flavor-universal non-standard neutrino interactions in future observations of diffuse neutrinos from all the past SNe, known as the diffuse supernova neutrino background (DSNB). According to our analysis, observations of the DSNB in HK, JUNO and DUNE experiments can probe such couplings by a factor of $\sim 2$ beyond the SN 1987A constraint. However, our result is also subject to a large uncertainty concerning the precise estimation of the DSNB.
