ResumenWith full data set that corresponds to an integrated luminosity of 9.4 fb−1, CDF has updated the top quark forward-backward asymmetry (FBA) as functions of rapidity difference |Δy| and tt invariant mass Mtt. Beside the sustained inconsistency between experiments and standard model (SM) predictions at large |Δy| and Mtt, an unexpected large first Legendre moment with a1=0.39±0.108 is found. In order to solve the large top FBA, we study the contributions of color triplet scalar and color octet vector boson. We find that the top FBA at |Δy|>1 and Mtt>450 GeV in triplet and octet model could be enhanced to be around 30% and 20%, whereas the first Legendre moment is aDi1=0.38 and a1Axi=0.23, respectively.
