Finite energy QCD sum rules involving both inverse and positive moment integration kernels are employed to determine the bottom quark mass. The result obtained in the MS¯ scheme at a reference scale of 10GeV is m¯b(10GeV)=3623(9)MeV. This value translates into a scale invariant mass m¯b(m¯b)=4171(9)MeV. This result has the lowest total uncertainty of any method, and is less sensitive to a number of systematic uncertainties that affect other QCD sum rule determinations.
