Resumen

In this work, we propose new five-zero textures for the mass matrices in the lepton sector in order to get theoretical values for the neutrino masses. In our approach, we go beyond the standard model by assuming Dirac masses for the neutrinos, this feature allows us to make a theoretical prediction for the lightest neutrino mass in the normal and inverted ordering.These textures have enough free parameters to adjust the $U_{\text{\tiny PMNS}}$ mixing matrix and the charged lepton masses. The weak basis transformation which is a well-known technique to analyze textures and their implications for neutrino physics, by this method the lightest neutrino mass consistent with the restrictions coming from the zeros of the mass matrices is found between $\approx 5.9\:meV<m_{n_e}<3.5\:meV$ for the normal ordering, and $\approx 2.2\times10^{-2}\:eV<m_{n_\tau}<2.6\times10^{-2}\:eV$ for the inverted ordering.
