Abstract

We determine the mass of the bottom quark from high moments of the bb- production cross section in e+e- annihilation, which are dominated by the threshold region. On the theory side next-to-next-to-next-to-leading order (NNNLO) calculations both for the resonances and the continuum cross section are used for the first time. We find mbPS(2GeV)=4.532-0.039+0.013GeV for the potential-subtracted mass and mbMS(mbMS)=4.193-0.035+0.022GeV for the MS- bottom-quark mass.
