Description

With the help of a full Euler-like block parametrization of the flavor structure for the canonical seesaw mechanism, we present the first general and explicit analytical calculations of the light neutrino mass-squared differences, flavor mixing angles and leptonic CP violation responsible for the primary behaviors of neutrino oscillations. Such model-independent results will pave the way for testing the seesaw mechanism and probing its original parameter space at low energies.
