Through leptogenesis, baryogenesis could have the same origin as neutrino masses. Emphasis is put on the conditions which, in order that this mechanism works, need to be ful lled by the neutrino masses as well as by the heavy state masses. The model dependence of these conditions is discussed. N1 2
The basics of neutrino oscillations is discussed. The importance of the time-energy uncertainty relation is stressed. Neutrino oscillations in the leading approximation and evidence for neutrino oscillations are briefly summarized.
We study a model for the mass matrices of the leptons, based on texture zero elements. We are able to relate the mass eigenvalues of the charged leptons and of the neutrinos to the mixing angles, and can predict the masses of the neutrinos. We find a normal hierarchythe masses are 0.005 eV, 0.01 eV
