【 摘 要 】

The observed masses and mixings in the neutrino sector suggest an approximate μ - τ symmetry in the neutrino mass matrix. We explore the corresponding parameter space linked to a small breaking of this symmetry to show that in such a scenario neutrino masses must be quasi degenerated, whereas Majorana CP phases shall be non zero and strongly correlated to the Dirac CP phase.
