The b-quark mass from non-perturbative Nf=2Nf=2 Heavy Quark Effective Theory at O(1/mh)O(1/mh)

We report our final estimate of the b-quark mass from Nf=2Nf=2 lattice QCD simulations using Heavy Quark Effective Theory non-perturbatively matched to QCD at O(1/mh)O(1/mh). Treating systematic and statistical errors in a conservative manner, we obtain m¯bMS¯(2 GeV)=4.88(15) GeV after an extrapolation to the physical point.
