Majorana型中微子质量矩阵导出了一类轻子数破坏过程。这些反应的横截面的中微子质量矩阵元素，并估计一个半现实的事件率。这些过程提供了中微子振荡实验无法直接获得的质量和混合参数。如果这些过程被发现的速率比这里给出的更大，这将意味着一个新的物理轻子数违反不直接相关的马约拉纳中微子质量，如超对称模型中的R-宇称违反运营商。
A Majorana type of the neutrino mass matrix induces a class of lepton number violating processes. Cross sections of these reactions are given in terms of the neutrino mass matrix element, and a semi-realistic event rate is estimated. These processes provide mass and mixing parameters not directly accessible by the neutrino oscillation experiments. If these processes are discovered with a larger rate than given here, it would imply a new physics of the lepton number violation not directly related to the Majorana neutrino mass, such as R-parity violating operators in SUSY models.
