Bottom quark mass from QCD sum rules for the Upsilon system

Abstract

The talk presents an update of the bottom quark mass determination from QCD moment sum rules for the Upsilon system by the authors. Employing the MS_bar scheme, we find m_b(m_b) = 4.19 +- 0.06 GeV. The differences to our previous analysis will be discussed and we comment on the determination of the pole mass for the bottom quark.
