TTP - TTP07-29 NNNLO corrections to the toponium and bottomonium wave-functions at the origin

Institute for Theoretical Particle Physics (TTP)

We report new results of the NNNLO correction to the S-wave quarkonium wave-functions at the origin, which also provide an estimate of the resonance cross section in t-tbar threshold production at the ILC.
