IceCube轻无菌中微子的特征

Signature of light sterile neutrinos at IceCube

Bhavesh Chauhan, Subhendra Mohanty

摘要:

MiniBooNe合作最近报告了具有大混合角的轻无菌中微子的证据,从而证实了20年前LSND的测量结果。这种状态将直接与BBN $N_{eff}$的普朗克测量相冲突,除非在无菌扇区中存在自相互作用。我们的目标是调查这种相互作用是否会导致宇宙成因中微子光谱的共振吸收及其对冰立方实验的影响。我们表明,它是可能的,以提供独立的界限不育中微子参数空间从IceCube的观测与相应的中微子质量的频谱中的倾角。

英文摘要:

The MiniBooNe collaboration has recently reported evidence for a light sterile neutrino with large mixing angles thus corroborating the measurement by LSND twenty years ago. Such a state would be directly in conflict with Planck measurement of BBN $N_{eff}$ unless there is self-interaction in the sterile sector. Our objective is to investigate if such interactions could result in resonant absorption in the cosmogenic neutrino spectrum and its consequences for the IceCube experiment. We show that it is possible to give independent bounds on sterile neutrino parameter space from IceCube observations with the dips in the spectrum corresponding to the neutrino masses.
