The QED Initial State Corrections to the Forward-Backward Asymmetry of $e^{+}{e}^{-}\to {\gamma }^{\ast }/Z^{0\ast }$ to Higher Orders

J. Blümlein, A. De Freitas, K. Schönwald

The QED initial state corrections are calculated to the forward-backward asymmetry for $e^{+}{e}^{-}\to {\gamma }^{\ast }/{Z^0}^{\ast }$ in the leading logarithmic approximation to $O({\alpha }^6{L}^6)$ e…
