Resumen

The basic block In this work, we consider some of the phenomenological consequences of having Dirac neutrino masses instead of Majorana masses as assumed in most of the current literature. In order to carry out this analysis, we propose new five-zero textures for the mass matrices of the lepton sector. From our approach, we find new values for the neutrino masses in both, the normal and inverted hierarchy. These zero textures reproduce the U pmns mixing matrix and deliver relationships between the mixing angles and the lepton masses. In order to have reliable results, we have used two different procedures. The first method is based on a least-squares analysis to adjust the lepton masses and the mixing parameters to their corresponding experimental values. The second approach corresponds to the weak basis transformation which is a well-known technique to analyze textures and their implications for neutrino physics. Both the first and second method are consistent with a lightest neutrino mass equal to 4 meV and 3.7 meV, respectively.
