论文摘要
We computed the $Σ^{-}\to nπ^+e^-\ell^-$ ($\ell=e,μ$), $Ξ^-\to Λπ^+e^-e^-$, and $Λ\to pπ^+e^-e^-$ lepton number violating (LNV) hyperon decays mediated by a resonant Majorana neutrino.预期的超子生产速率（例如$ 10^6-10^8 $）的BES-III（BES-III）可能允许以足够的敏感性搜索这些罕见的超子衰减。我们说明了从这些超子通道得出的新的重型混合参数的限制，并将它们与谐振中微子状态相似的质量区域的其他LNV介子衰变进行了比较。
We computed the $Σ^{-}\to nπ^+e^-\ell^-$ ($\ell=e,μ$), $Ξ^-\to Λπ^+e^-e^-$, and $Λ\to pπ^+e^-e^-$ lepton number violating (LNV) hyperon decays mediated by a resonant Majorana neutrino. The expected hyperon production rate of experiments like BES-III of around $10^6-10^8$ may allow searching for these rare hyperon decays at enough sensitivities. We illustrate the limits on the new heavy mixing parameters derived from these hyperon channels and compare them with other LNV meson decays in similar mass regions of the resonant neutrino state.
