Description

We will present precise determinations for the b-quark mass, the quark mass ratios mb/mc and mb/ms as well as the leptonic B-decay constants employing lattice QCD methods. We use the gauge configurations with four dynamical quark flavors, up/down, strange and charm, generated by the European Twisted Mass Collaboration. Our results, obtained at three values of the lattice spacing, are extrapolated to the physical pion mass and to the continuum limit.
