We discuss the phenomenology of effective field theories with new scalar or
vector representations of the Standard Model quark flavor symmetry group,
allowing for large flavor breaking involving the third generation. Such field
content can have a relatively low mass scale \lesssim TeV and O(1) couplings to
quarks, while being naturally consistent with both flavor violating and flavor
diagonal constraints. These theories therefore have the potential for early
discovery at LHC, and provide a flavor safe "tool box" for addressing anomalies
at colliders and low energy experiments. We catalogue the possible flavor
symmetric representations, and consider applications to the anomalous Tevatron
t-tbar forward backward asymmetry and B_s mixing measurements, individually or
concurrently. Collider signatures and constraints on flavor symmetric models
are also studied more generally. In our examination of the t-tbar forward
backward asymmetry we determine model independent acceptance corrections
appropriate for comparing against CDF data that can be applied to any model
seeking to explain the t-tbar forward backward asymmetry.Comment: 71 pages, 14 Figures, 12 Table
