Solving the mystery of neutrino mass with random matrix theory.

Researchers from Osaka Metropolitan University have used random matrix theory to explain the neutrino mass hierarchy. They analyzed the neutrino mass matrix by randomly assigning each element of the matrix and found that the lepton flavor mixings are large. The researchers were able to prove that the calculation of the squared difference of the neutrino masses is closest to the experimental results in the case of the seesaw model with the random Dirac and Majorana matrices. However, the proof is not mathematically complete and is expected to be rigorously proven as random matrix theory continues to develop.
