  "abstract": "In this paper, forward-backward asymmetry and differential cross section of top quark in flavor violating $Z'$ model up to $\\mathscr{O}(\\alpha_s^2 \\alpha_X)$ at Tevatron are calculated. In order to account for the top observed large forward-backward asymmetry, the new coupling $g_X$ among $Z'$ and quarks will be not much less than strong coupling constant $g_s$. After including the new higher order correction, the differential cross section can fit the data better than those only including the leading contributions from $Z'$, while the forward-backward asymmetry is still in agreement with the measurement.",
