abstract
We perform a systematic and complete analysis of texture zeros in the lepton mass matrices and identify all viable and maximally restrictive cases of pairs (M_\ell, M_D) and (M_\ell, M_L), where M_\ell, M_D and M_L are the charged-lepton, Dirac neutrino and Majorana neutrino mass matrices, respectively. To this end, we perform a thorough analysis of textures which are equivalent through weak-basis permutations. Furthermore, we introduce numerical measures for the predictivity of textures and apply them to the viable and maximally restrictive texture zero models. It turns out that for Dirac neutrinos these models can at most predict the smallest neutrino mass and the CKM-type phase of the mixing matrix. For Majorana neutrinos most models can, in addition, predict the effective neutrino mass for neutrinoless double beta decay. Apart from one model, which has marginal predictive power with respect to sin^2(theta_23), no other model can predict any of the already measured observables.

Several one-zero neutrino textures remain compatible with oscillation data and generate the baryon asymmetry via resonant Type-II leptogenesis with flavor-resolved Boltzmann evolution.
A new minimal neutrino mass matrix texture is introduced that enforces equal Majorana phases within a partial TBM scheme and is realized via hybrid Type-I and Type-II seesaw under an extended discrete symmetry.
Numerical scans in the minimal scotogenic model indicate that approximate neutrino texture structures emerge dynamically from dark matter and lepton flavor violation consistency conditions.
