Description
If neutrino tribimaximal mixing is explained by a non-Abelian discrete symmetry such as A4, T7, Δ(27), etc., the charged-lepton Higgs sector has a Z3 residual symmetry (lepton flavor triality), which may be observed directly in the decay chain H0→ψ20ψ20, then ψ20(ψ20)→li+lj-(i≠j), where H0 is a standard-model-like Higgs boson and ψ20 is a scalar particle needed for realizing the original discrete symmetry. If kinematically allowed, this unusual and easily detectable decay is observable at the LHC with 1 fb-1 for Ecm=7 TeV.
