Confronting predictive texture zeros in lepton mass matrices with current data

High Energy Physics - Phenomenology 2015-07-08 v2

Abstract

Several popular Ans\"atze of lepton mass matrices that contain texture zeros are confronted with current neutrino observational data. We perform a systematic χ2\chi^2-analysis in a wide class of schemes, considering arbitrary Hermitian charged lepton mass matrices and symmetric mass matrices for Majorana neutrinos or Hermitian mass matrices for Dirac neutrinos. Our study reveals that several patterns are still consistent with all the observations at 68.27% confidence level, while some others are disfavored or excluded by the experimental data. The well-known Frampton-Glashow-Marfatia two-zero textures, hybrid textures and parallel structures, among others, are considered.
