论文摘要
引入了一种名为Maparon的新的金石粒子，以通过一些新的物理模型来解释中微子质量的起源，假设中微子是主要的粒子。通过扩展信号区域并使用似然分析，可以在最初旨在搜索$μ-E $转换的实验中搜索Maparon。对于彗星实验，过程$μ\ rightArrow ej $的灵敏度能够达到$ {\ Mathcal {b}}}（μ\ rightarrow ej）= 2.3 \ times 10^{ - 5} $ in Chase-I和$ o（10^{ - 8}）$ in PHAPE-II中的$。同时，本文还讨论了在未来实验中搜索Maporon的敏感性。
A new Goldstone particle named Majoron is introduced in order to explain the origin of neutrino mass by some new physics models assuming that neutrinos are Majorana particle. By expanding signal region and using likelihood analysis, it becomes possible to search for Majoron at experiments that is originally designed to search for $μ-e$ conversion. For the COMET experiment, the sensitivity of process $μ\rightarrow eJ$ is able to reach ${\mathcal{B}}(μ\rightarrow eJ)=2.3\times 10^{-5}$ in Phase-I and $O(10^{-8})$ in Phase-II. Meanwhile, the sensitivities to search for Majoron at future experiments are also discussed in this article.
