摘要：
The lepton sector masses and mixing angles can be explained in models based on A(4) symmetry. A(4) is a non-Abelian discrete group. Therefore, one issue in constructing models based on it is explaining the origin of A(4). A plausible mechanism is that A(4) is an unbroken subgroup of a continuous group that is broken spontaneously. We construct a model of leptons where the A(4) symmetry is obtained by spontaneous symmetry breaking of SO(3).
