"Explaining the Tevatron ttbar asymmetry with light axigluons"

The forward-backward asymmetry of ttbar pair production at the Tevatron remains the most startling potential signal of new physics to date. In this talk I review a range of models that have been introduced to explain the anomaly and discuss experimental constraints on those new physics models. I then explore the feasibility of explaining the ttbar asymmetry with a light axigluon, and discuss search strategies for such an axigluon at the LHC.
