# Common origin of fermion mixing and geometrical CP violation, and its test through Higgs physics at the LHC.

We construct for the first time a flavor model, based on the smallest discrete symmetry Δ(27) that implements spontaneous CP violation with a complex phase of geometric origin, which can actually reproduce all quark masses and mixing data. We show that its scalar sector has exotic properties that can be tested at the LHC.
