We report our final estimate of the b-quark mass from Nf=2 lattice QCD simulations using Heavy Quark Effective Theory non-perturbatively matched to QCD at O(1/mh). Treating systematic and statistical errors in a conservative manner, we obtain View the MathML source after an extrapolation to the physical point.
