Corrections of $O \alpha_{s}^{2}$ to the Forward-Backward Asymmetry
We calculate the second-order QCD corrections to the forward-backward asymmetry in $e^+e^-$ annihilation. Using the quark axis definition, we do not agree with either existing calculation, but the difference relative to one of them is small and understood. In particular, we point out that the forwar...
