Abstract
We construct a supersymmetric model based on ${T}^{\ensuremath{'}}\ensuremath{\bigotimes}{Z}_{3}\ensuremath{\bigotimes}{Z}_{9}$ flavor symmetry. At the leading order, the charged lepton mass matrix is not diagonal, ${T}^{\ensuremath{'}}$ is broken completely, and the hierarchy in the charged lepton masses is generated naturally. Nearly tribimaximal mixing is predicted, and subleading effects induce corrections of order ${\ensuremath{\lambda}}^{2}$, where $\ensuremath{\lambda}$ is the Cabibbo angle. Both the up quark and down quark mass matrices' textures of the well-known $\mathrm{U}(2)$ flavor theory are produced at the leading order; realistic hierarchies in quark masses and Cabibbo-Kobayashi-Maskawa matrix elements are obtained. The vacuum alignment and subleading corrections are discussed in detail.
