Abstract
The top-quark threshold cross section at colliders near production threshold is investigated. We study the scale dependence of the cross section for ) near and discuss the theoretical accuracy of the NNNLO prediction. We report that a threshold scan at an collider would allow a determination of the top-quark mass with an accuracy of order 30 MeV.
