Bottom Quark Mass Determination from low-n Sum Rules
Gennaro Corcella, Andre H. Hoang
Abstract
We study the uncertainties in the MSbar bottom quark mass determination using relativistic sum rules to O(alphaS2). We include charm mass effects and secondary b bbar production and treat the experimental continuum region more conservatively than previous analyses. The PDG treatment of the region between the resonances Upsilon (4S) and Upsilon (5S) is reconsidered. Our final result reads: mb(mb)=(4.20 0.09) GeV.
