title = "The bottom {\=M}{\=S} quark mass from sum rules at next-to-next-to-leading order",
abstract = "We determine the bottom {\=M}{\=S} quark mass {\=m}(b) and the quark mass in the potential subtraction scheme from moments of the b{\=b} production cross section and from the mass of the Upsilon 1S state at next-to-next-to-leading order in a reorganized perturbative expansion that sums Coulomb exchange to all orders. We find {\=m}(b)({\=m}(b)) = (4.25 ± 0.08)GeV and m(b,PS)(2 GeV) = (4.59 ± 0.08)GeV for the potential-subtracted mass at the scale 2 GeV, adopting a conservative error estimate.
