Three-Neutrino Mass Matrices with Two Texture Zeros
Three-Neutrino Mass Matrices with Two Texture Zeros
Out of the 15 3 × 3 neutrino mass matrices with two texture zeros, seven are compatible with the neutrino oscillation data. While two of them correspond to hierarchical neutrino masses and 1 to an inverted hierarchy, the remaining four correspond to degenerate masses. Moreover only the first three of …
