摘要：
This letter presents results for higher order corrections to the forward-backward asymmetry AFB. The first order QED corrections are taken into account completely, the order α2 corrections are considered in the leading log approximation, while soft photons are resummed. Pure weak corrections are also included. Two definitions for AFB are discussed. Results are given without cuts and including realistic energy and acollinearity cuts. The calculation achieves the required level of accuracy. © 1990.
