摘要

We present a simple, perturbative, and renormalizable model with a flavor symmetry which can explain both the t (t) over bar forward-backward asymmetry and the bump feature present in the dijet mass distribution of the W + jj sample in the range 120-160 GeV that was recently reported by the CDF collaboration. The flavor symmetry not only ensures the flavor/CP safety of the model, but also relates the two anomalies unambiguously. It predicts a comparable forward-backward asymmet
