超新星中微子中自诱导光谱均衡与普通物质效应的模型无关诊断
Model-independent diagnostic of self-induced spectral equalization versus ordinary matter effects in supernova neutrinos
摘要：
超新星（SN）核心附近的自诱导味转换可以使不同中微子种类的通量变得几乎相等，从而可能改变SN爆炸的动力学并消除所有进一步的中微子振荡效应。我们提出了一个新的模型独立的分析策略，为下一个银河SN信号，将区分这种味道均衡的情况下，从物质的影响，只有在SN吸积阶段的情况。我们的方法不依赖于拟合或建模的能量依赖的不同物种的注量的一个已知的功能，而是使用一个模型独立的比较充电电流和中性电流事件在大型下一代地下探测器。具体来说，我们主张，由于在闪烁体探测器，这是不敏感的振荡效应，并可以用作一个独立的模型归一化质子上的弹性散射的事件，应与事件相比，由于逆β衰变的$\barν_e$在水切伦科夫探测器和/或事件由于带电电流相互作用的$ν_e$在氩探测器。在这些不同的检测通道的事件的比率允许一个区分一个完整的味道均衡从纯物质的效果，无论是中微子质量排序，只要不同的物种之间的光谱差异不是太小。
英文摘要：
Self-induced flavor conversions near the supernova (SN) core can make the fluxes for different neutrino species become almost equal, potentially altering the dynamics of the SN explosion and washing out all further neutrino oscillation effects. We present a new model-independent analysis strategy for the next galactic SN signal that will distinguish this flavor equalization scenario from a matter effects only scenario during the SN accretion phase. Our method does not rely on fitting or modelling the energy-dependent fluences of the different species to a known function, but rather uses a model-independent comparison of charged-current and neutral-current events at large next-generation underground detectors. Specifically, we advocate that the events due to elastic scattering on protons in a scintillator detector, which is insensitive to oscillation effects and can be used as a model-independent normalization, should be compared with the events due to inverse beta decay of $\barν_e$ in a water Cherenkov detector and/or the events due to charged-current interactions of $ν_e$ in an Argon detector. The ratio of events in these different detection channels allow one to distinguish a complete flavor equalization from a pure matter effect, for either of the neutrino mass orderings, as long as the spectral differences among the different species are not too small.
