Two Component Dark Matters in S4 x Z2 Flavor Symmetric Extra U(1)

We study cosmic-ray anomaly observed by PAMELA based on E-6 inspired extra U(1) model with S-4 X Z(2) flavor symmetry. In our model, the lightest flavon has a very long lifetime of O(10(18)) second which is longer than the age of the universe, but not long enough to explain the PAMELA result similar to O(10(26)) sec. Such a situation could be avoidable by considering that the flavor) is not the dominant component of dark matters and the dominant one is the lightest neutralino. With an appropriate parameter set, the density parameter of the dark matter and the over-abundance of the positron flux in the cosmic ray are realized at the same time. There is an interesting correlation between spectrum of positron flux and V-MNS. No excess of anti-proton in cosmic ray suggests that sfermions are heavier than 4 TeV and the masses of the light Higgs bosons are degenerated.
