通过探测超新星中微子获取中微子参数信息

Acquire information about neutrino parameters by detecting supernova neutrinos

Ming-Yang Huang, Xin-Heng Guo, Bing-Lin Young

摘要:

我们考虑了超新星激波效应、Mikheyev-Smirnov-Wolfenstein(MSW)效应、集体效应和地球物质效应对地球上II型超新星中微子探测的影响。结果表明,超新星中微子事件数与中微子质量等级、中微子混合角$θ_{13}$和中微子质量有关。因此,我们提出了可能的方法来确定质量等级,并获得有关$θ_{13}$和中微子质量的信息,通过检测超新星中微子。我们将这些方法应用到当前的一些中微子实验中。

英文摘要:

We consider the supernova shock effects, the Mikheyev-Smirnov-Wolfenstein (MSW) effects, the collective effects, and the Earth matter effects in the detection of type II supernova neutrinos on the Earth. It is found that the event number of supernova neutrinos depends on the neutrino mass hierarchy, the neutrino mixing angle $θ_{13}$, and neutrino masses. Therefore, we propose possible methods to identify the mass hierarchy and acquire information about $θ_{13}$ and neutrino masses by detecting supernova neutrinos. We apply these methods to some current neutrino experiments.
