Predictions from Heavy New Physics Interpretation of the Top Forward-Backward Asymmetry

Understand

We derive generic predictions at hadron colliders from the large forward-backward asymmetry observed at the Tevatron, assuming the latter arises from heavy new physics beyond the Standard Model.

• We use an effective field theory approach to characterize the associated unknown dynamics.
• By fitting the Tevatron t \bar t data we derive constraints on the form of the new physics.
• Furthermore, we show that heavy new physics explaining the Tevatron data generically enhances at high invariant masses both the top pair production cross section and the charge asymmetry at the LHC.
