Tri-Permuting Mixing Matrix and predictions for theta_13
  We introduce a new texture for neutrino mixing named Tri-Permuting (TP) mixing matrix. This pattern is characterized by maximal solar and atmospheric angles and by a large reactor angle satisfying sin(theta_13)=1/3. The correct lepton mixing matrix is obtained when combining the charged lepton mixing matrix with the neutrino one. In this way we get new predictions for theta_13 with respect to those obtained by the well studied TBM or BM mixing patterns. We present a specific model that gives rise to TP mixing in the neutrino sector as well as the required corrections from the charged lepton one.
