重无菌中微子和超新星爆炸

Heavy sterile neutrinos and supernova explosions

George M. Fuller, Alexander Kusenko, Kalliopi Petraki

摘要:

我们考虑静止质量~0.2 GeV的无菌中微子。这种无菌中微子可以通过增强从核心到冲击波阵面附近的能量传输来增加核心坍缩超新星冲击波能量。这些中微子的衰变可能会产生一个非常活跃的中微子流,未来可以从银河系超新星的中微子观测中检测到。不育中微子质量和混合角的相关范围可以在未来的实验室实验中探索。

英文摘要:

We consider sterile neutrinos with rest masses ~0.2 GeV. Such sterile neutrinos could augment core collapse supernova shock energies by enhancing energy transport from the core to the vicinity of the shock front. The decay of these neutrinos could produce a flux of very energetic active neutrinos, detectable by future neutrino observations from a galactic supernova. The relevant range of sterile neutrino masses and mixing angles can be probed in future laboratory experiments.
