Early black hole formation in a core-collapse supernova will abruptly truncate the neutrino fluxes. The sharp cutoff can be used to make model-independent time-of-flight neutrino mass tests. Assuming a neutrino luminosity of 10(52) erg/s per flavor at cutoff and a distance of 10 kpc, Super-Kamiokande can detect an electron neutrino mass as small as 1.8 eV, and the proposed OMNIS detector can detect mu and tau neutrino masses as small as 6 eV. We present the first technique with direct sensitivity to eV-scale mu and tau neutrino masses.
核心坍缩超新星中早期黑洞的形成将突然截断中微子通量。这种急剧截断可用于进行与模型无关的飞行时间中微子质量测试。假设截止时每种味的中微子光度为10(52)尔格/秒，距离为10千秒差距，超级神冈探测器能够探测到低至1.8电子伏特的电子中微子质量，而提议的全向探测器能够探测到低至6电子伏特的μ子和τ子中微子质量。我们提出了第一种对电子伏特尺度的μ子和τ子中微子质量具有直接灵敏度的技术。
