Axigluon as possible explanation for pp¯→tt¯ forward-backward asymmetry

A flavor-nonuniversal chiral color model is introduced. It is used for comparison to the recent data on p¯p→t¯t. We concluded that the data are consistent with interpretation as an axigluon exchange within 1σ and a unique rise and fall behavior is predicated with regard to the asymmetry AFBt as a function of tt¯ invariant mass, which can distinguish our model from others before one discovers the axigluon resonance. Further aspects of the model are discussed.
