利用未来中微子信号鉴别超新星模型的展望

Prospects for Distinguishing Supernova Models Using a Future Neutrino Signal

Jackson Olsen, Yong-Zhong Qian

摘要:

下一个银河系核心坍缩超新星(SN)应该会产生大量观测到的中微子。使用贝叶斯技术,我们表明,与SN在一个已知的距离高达25千秒差距,中微子事件在水切伦科夫探测器类似的超级神冈(SK)可以用来区分七个一维中微子发射模型假设没有味振荡或标准的米赫耶夫-斯米尔诺夫-沃尔芬斯坦效应。其中一些模型仍然可以用已知距离为50千秒差距的SN来区分。我们还考虑了中微子能量和到达时间的相对分布模型预测,并发现一个检测器,如SK满足的要求,以区分这些分布与SN在一个未知的距离高达$\sim 10$ kpc。

英文摘要:

The next Galactic core-collapse supernova (SN) should yield a large number of observed neutrinos. Using Bayesian techniques, we show that with an SN at a known distance up to 25 kpc, the neutrino events in a water Cherenkov detector similar to Super-Kamiokande (SK) could be used to distinguish between seven one-dimensional neutrino emission models assuming no flavor oscillations or the standard Mikheyev-Smirnov-Wolfenstein effect. Some of these models could still be differentiated with an SN at a known distance of 50 kpc. We also consider just the relative distributions of neutrino energy and arrival time predicted by the models and find that a detector like SK meets the requirement to distinguish between these distributions with an SN at an unknown distance up to $\sim 10$ kpc.
