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