论文摘要

太阳中微子可以有效地向上扫描至MEV尺度重型中性瘦素(HNLS)。然后,HNL可以腐烂到电子峰值对,从而导致大批次探测器内的能量沉积。在本文中,我们考虑了太阳中微子的质量群体向上散射到质量20 mev $ \ geq m_n \ geq 2 m_e $的质量。地球的大容量弥补了HNL的长衰减长度,导致可观察的率为$ n \rightarrowν_αe^+e^ - 在大容量检测器中。我们发现,搜索地幔向上散射的HNL可以将新颖的限制与第三代瘦素混合,$ | u_ {τn} | $在MEV制度中的群众;对与第一代和第二代瘦素混合的敏感性与现有搜索策略没有竞争力。

Solar neutrinos can be efficiently upscattered to MeV scale heavy neutral leptons (HNLs) within the Earth's mantle. HNLs can then decay to electron-positron pairs leading to energy deposition inside large-volume detectors. In this paper we consider mass-portal upscattering of solar neutrinos to HNLs of mass 20 MeV $\geq m_N \geq 2 m_e$. The large volume of the Earth compensates for the long decay-length of the HNLs leading to observable rates of $N\rightarrow ν_αe^+e^-$ in large volume detectors. We find that searches for mantle-upscattered HNLs can set the novel limits on mixing with third generation leptons, $|U_{τN}|$ for masses in the MeV regime; sensitivity to mixing with first- and second-generation leptons is not competitive with existing search strategies.
