We consider new physics explanations of the anomaly in the forward-backward asymmetry measured at the Tevatron, in the context of flavor conserving models. The recently measured LHC dijet distributions strongly constrain many otherwise viable models. A new scalar particle in the representation of flavor and color can fit the asymmetry and cross section data at the Tevatron and avoid both low-and high-energy bounds from flavor physics and the LHC. An s-channel resonance in uc → uc scattering at the LHC is predicted to be not far from the current sensitivity. This model also predicts rich top quark physics for the early LHC from decays of the new scalar particles. Single production gives signatures with high p jet T and pair production leads to and 4 jet final states.
