Query: Bottom quark mass and alpha_s from the Upsilon system   The mass of the bottom quark and the strong coupling constant alpha_s are
determined from QCD moment sum rules for the Upsilon system. Two analyses are
performed using both the pole mass M_b as well as the mass m_b in the $\MSb$
scheme. In the pole-mass scheme large perturbative corrections resulting from
coulombic contributions have to be resummed. In the $\MSb$ scheme this can be
avoided by an appropriate choice for the renormalization scale. For the bottom
quark mass we obtain M_b = 4.60 +- 0.02 GeV and m_b(m_b) = 4.13 +- 0.06 GeV.
Our combined result from both determinations for the strong coupling is
alpha_s(M_Z) = 0.119 +- 0.008.
