Description

Decays of B mesons scale with high powers of the bottom quark mass. To avoid large parametric uncertainties precise knowledge of this parameter is important. We determine the mass of the bottom quark from moments of the $b\bar{b}$ production cross section near threshold. On the theory side we use NNNLO predictions both for the resonances and the continuum cross section. We compare our result to other recent precision determinations.
