摘要:We report about the status of the on-going project tackled by the ALPHA Collaboration to measure from lattice QCD simulations with Nf = 2 dynamical quarks the b quark mass and the B meson decay constant. We have performed the computation in the framework of Heavy Quark Effective Theory expanded at 1/m order; we have matched it to QCD using a non-perturbative approach. We have considered several lattice spacings and light quark masses in order to control cut-off effects and extrapolate to the chiral limit.
