Title: Forward-backward asymmetry and the differential cross section of the top quark in the flavor violating Z{sup '} model at O({alpha}{sub s}{sup 2{alpha}}{sub X})

Abstract

In this paper, forward-backward asymmetry and differential cross section of top quark in flavor violating Z{sup '} model up to O({alpha}{sub s}{sup 2{alpha}}{sub X}) at Tevatron are calculated. In order to account for the top observed large forward-backward asymmetry, the new coupling g{sub X} among Z{sup '} and quarks will be not much less than strong coupling constant g{sub 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{sup '}, while the forward-backward asymmetry is still in agreement with the measurement.
