Implications of the CDF tt̄ forward-backward asymmetry for hard top physics

Research output: Contribution to conferencePosterpeer-review

Abstract

The CDF collaboration has recently reported a large deviation from the standard model of the tt
¯ forward-backward asymmetry in the high
invariant mass region. We interpret this measurement as coming from new physics at a heavy scale Λ, and perform a model-independent
analysis up to O(1/Λ4). We find that a large asymmetry can only be accommodated by heavy new physics that interfere with the standard
model. In addition, the new physics induces a minimal enhancement of boosted jets. We show that a smoking gun test for the heavy new
physics hypothesis is a significant deviation from the standard model prediction for the tt
¯ differential cross section at large invariant mass.
