Abstract
The mass of the bottom quark can be determined with high precision from moments of the pair-production cross section σ(e+e− → bb¯) near threshold. We present the first complete NNNLO determination from non-relativistic sum rules, obtaining a bottom-quark mass of mPS b (2GeV) = 4.532+ − 0 0 013 039GeV in the potential-subtracted scheme. For the mass in the MS scheme we find mMS b (mMS b ) = 4.203+ − 0 0 016 034GeV using the recently computed four-loop correction to the scheme conversion.
