Abstract The PMNS neutrino mixing matrix U PMNS is in general a product of two unitary matrices U lep and U ν arising from the diagonalization of the charged lepton and neutrino mass matrices, U PMNS =U † lep U ν . Assuming that U ν is a bimaximal mixing matrix, we investigate the possible forms of U lep . We identify three possible generic structures of U lep , which are compatible with the existing data on neutrino mixing. One corresponds to a hierarchical “CKM-like” matrix. In this case… Expand
