Predictions of the most minimal see-saw model

We derive the most minimal see-saw texture from an extra-dimensional dynamics. It predicts theta(13) = 0.078 +/- 0.015 and m(ee) = 2.6 +/- 0.4 meV. Assuming thermal leptogenesis, the sign of the CP-phase measurable in neutrino oscillations, together with the sign of baryon asymmetry, determines the order of heavy neutrino masses. Unless heavy neutrinos are almost degenerate, successful leptogenesis fixes the lightest mass. Depending on the sign of the neutrino CP-phase, the supersymmetric version of the model with universal soft terms at high scale predicts BR(mu --> egamma) or BR(tau --> mugamma), and gives a lower bound on the other process.
