黑洞坍缩过程中超新星中微子的振荡与未来探测

Oscillation and Future Detection of Failed Supernova Neutrinos from Black Hole Forming Collapse

摘要:

最近,恒星坍缩涉及大质量恒星形成黑洞,被认为会释放出与普通核心坍缩超新星相当的巨大中微子通量。我们调查他们的可探测性目前正在运行的中微子探测器,SuperKamiokande。中微子振荡也被考虑在内的评估。我们发现,事件数大于或相当于超新星中微子,因此,黑洞形成也是中微子天文学的候选人。此外,我们还发现事件数主要取决于计算黑洞形成时所用的状态方程。这一事实意味着,探测从黑洞祖先发射的中微子对于探索热和/或致密物质的状态方程的性质是非常有价值的。

英文摘要:

Recently, stellar collapse involving black hole formation from massive stars is suggested to emit enormous fluxes of neutrinos on par with ordinary core-collapse supernovae. We investigate their detectability for the currently operating neutrino detector, SuperKamiokande. Neutrino oscillation is also taken into account for the evaluation. We find that the event number is larger than or comparable to that of supernova neutrinos and, hence, black hole formation is also a candidate for neutrino astronomy. Moreover, we find that the event number depends dominantly on the equation of state used in the computations of the black hole formation. This fact implies that the detection of neutrinos emitted from the black hole progenitors is very valuable to probe the properties of the equation of state for hot and/or dense matter.
