Query: Realizing Tri-bimaximal Mixing in Minimal Seesaw Model with S4 Family
  Symmetry   In this paper, we realize the tri-bimaximal mixing in the lepton sector in
the context of minimal seesaw in which only two right-handed neutrinos are
introduced, with the discrete group $S4$ as the family symmetry. In order to
constrain the form of superpotential, a $Z3$ symmetry is also introduced. In
the model, the mass matrices for charged leptons and right-handed neutrinos are
diagonal. The unitary matrix that diagonalizes the light Majorana neutrino mass
matrix is exact tri-bimaximal at LO, and is corrected by small quantities of
$\mathcal{O}(0.01)$ at NLO. The mechanism to get the particular scalar VEV
alignments used is also presented. Phenomenologically, the mass spectrum is of
normal hierarchy with $m_1=0$, and $\sum m_i$ and $|m_{ee}|$ are about $0.058
eV$ and $0.003 eV$ respectively.
