Third-order correction to top-quark pair production near threshold II. Potential contributions
M. Beneke, Y. Kiyo
We provide a detailed account of the methods and calculations for the third-order corrections to the S-wave Green function from heavy-quark potentials other than the Coulomb potent…

Third-order correction to top-quark pair production near threshold I. Effective theory set-up and matching coefficients
M. Beneke, Y. Kiyo, K. Schuller
This is the first in a series of papers, in which we compute the third-order QCD corrections to top-antitop production near threshold in e+ e- collisions. The present paper provide…
