Abstract

We use the threshold expansion and non-relativistic effective theory to determine the bottom quark mass from moments of the bb production cross section at next-to-next-to-leading order in the (resummed) perturbative expansion, and including a summation of logarithms. For the \rm MS mass m_b, we find m_b(m_b)=(4.26± 0.12) GeV.
