Bottom quark mass from QCD sum rules for the Upsilon system
arXiv:hep-ph/9810259 · doi:10.1016/S0920-5632(99)00182-6
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.
