Abstract

In this talk, we investigate Lepton Flavor Violating (LFV) tau decay by R-Parity Violating (RPV) operators controlled by a non-Abelian discrete Q₆ family symmetry. We assume that only a family symmetry determines the whole flavor structure of a model, and the model indicates specific predictions of LFV tau decay processes by RPV operators. We predict BR(τ→ 3e)/BR(τ→ 3 μ) ∼ 4 m_μ²/m_τ² in a Q₆ family symmetric model.
