论文摘要
巨大恒星的核心塌陷导致各种物理因素的命运不同，这给出了发射中微子的不同光谱。我们专注于超新星遗物中微子（SRN）作为研究恒星崩溃命运的探测器。我们介绍了恒星核心崩溃，典型的质量中子恒星，较高的质量中子恒星或基于不同状态的不同核方程形成黑洞的典型质量中子恒星，较高的质量中子星或失败的超新星，我们介绍了三个结果状态的检测器的SRN通量和事件速率光谱。然后将可能的SRN通量形成为三个组件的混合物。我们还显示了下一代水基Cherenkov探测器SK-GD和Hyper-Kamiokande的预期灵敏度，以限制混合物分数。这项研究提供了通过SRN测量来提取天体物理约束的实际例子。
Core collapse of massive stars leads to different fates for various physical factors, which gives different spectra of the emitted neutrinos. We focus on the supernova relic neutrinos (SRNs) as a probe to investigate the stellar collapse fate. We present the SRN fluxes and event rate spectra at a detector for three resultant states after stellar core collapse, the typical mass neutron star, the higher mass neutron star, or the failed supernova forming a black hole, based on different nuclear equations of state. Then possible SRN fluxes are formed as mixtures of the three components. We also show the expected sensitivities at the next-generation water-based Cherenkov detectors, SK-Gd and Hyper-Kamiokande, as constraining the mixture fractions. This study provides a practical example of extracting astrophysical constraints through SRN measurement.
