论文摘要
地球内部的太阳中微子向散射进行散射可以源不稳定的颗粒,这些颗粒可能会腐烂地面探测器。与幼稚的期望相反,我们表明,当衰减长度比\ emph {arter}(而不是检测器)的半径短得多时,事件速率与衰减长度无关。在本文中,我们研究了一个过渡偶极子操作员(中微子偶极子门户),并表明Borexino的现有数据探针以前在0.5--20 MEV状态下未接触过的参数空间,以补充最近的宇宙学和超新星界限。我们简要评论了与发光暗物质的相似性和差异,并评论了由大气中微子引起的类似信号的未来前景。
Solar neutrinos upscattering inside the Earth can source unstable particles that can decay inside terrestrial detectors. Contrary to naive expectations we show that when the decay length is much shorter than the radius of the \emph{Earth} (rather than the detector), the event rate is independent of the decay length. In this paper we study a transition dipole operator (neutrino dipole portal) and show that Borexino's existing data probes previously untouched parameter space in the 0.5--20 MeV regime, complementing recent cosmological and supernova bounds. We briefly comment on similarities and differences with luminous dark matter and comment on future prospects for analogous signals stemming from atmospheric neutrinos.
