Abstract

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 mbMS(2GeV)=4.88(15)GeV after an extrapolation to the physical point. © 2014 The Authors.
