Top quark mass determination near tt-bar threshold at lepton colliders
Description
Future e+e- linear colliders will enable us to determine the top quark mass with high accuracy from the measurement of the 1S peak position of (remnant of) toponium. The estimated statistical error in the measurement is about 50 MeV with integrated luminosity of 30 fb-1. We calculate O(αs5m) corrections to the quarkonium 1S energy spectrum in the large-β0 approximation to reduce theoretical uncertainties below the corresponding experimental error. We discuss the significance of the O(αs5m) corrections and estimate theoretical uncertainties of our prediction. (author)
