Majorana中微子质量矩阵的一零织构和当前的实验检验

The One-zero Textures of Majorana Neutrino Mass Matrix and Current Experimental Tests

E. I. Lashin, N. Chamoun

摘要:

根据最近的中微子振荡数据,我们对中微子质量矩阵的所有可能的1 - 0织构进行了全面系统的研究,这些数据暗示了最小混合角($θ_z$)有一个相对较大的非零值.我们发现,所有六种可能的一个零纹理都能够容纳的实验数据,与五种情况下也允许不可逆的质量矩阵。我们提出了对称实现的所有一个零奇异和非奇异模式的类型I和类型II的跷跷板机制计划。

英文摘要:

We carry out a complete and systematic study of all the possible one-zero textures for the neutrino mass matrix in light of the recent neutrino oscillation data which hint to a relatively large non-vanishing value for the smallest mixing angle ($θ_z$). We find that all the six possible one-zero textures are able to accommodate the experimental data, with five cases allowing also for non-invertible mass matrices. We present symmetry realizations for all the one-zero singular and non-singular patterns in type-I and type-II seesaw mechanism schemes.
