Abstract The studied conjecture is that ultra high energy cosmic rays (UHECRs) are hypothetical Planck neutrinos arising in the decay of the protons falling onto the gravastar. The proton is assumed to decay at the Planck scale into positron and four Planck neutrinos. The supermassive black holes inside active galactic nuclei, while interpreted as gravastars, are considered as UHECR sources. The scattering of the Planck neutrinos by the proton at the Planck scale is considered. The Planck neutrinos contribution to the CR events may explain the CR spectrum from 5 × 1018 eV to 1020 eV. The muon number in the Planck neutrinos-initiated shower is estimated to be larger by a factor of 3/2 in comparison with the standard model that is consistent with the observational data.

普朗克中微子作为超高能宇宙射线

摘要 研究的猜想是超高能宇宙射线（UHECRs）是质子落入引力星的衰变过程中产生的假想普朗克中微子。假设质子在普朗克尺度上衰变成正电子和四个普朗克中微子。活动星系核内的超大质量黑洞虽然被解释为引力星，但被认为是 UHECR 源。考虑了普朗克尺度下质子对普朗克中微子的散射。普朗克中微子对 CR 事件的贡献可以解释从 5 × 1018 eV 到 1020 eV 的 CR 谱。与观测数据一致的标准模型相比，普朗克中微子引发的流星雨中的 μ 子数估计要大 3/2 倍。
