m_b and f_Bs from a combination of HQET and QCD with unphysically light b-quarks — •Damiano Guazzini — DESY, Platanenallee 6, 15738 Zeuthen, Germany

We compute the decay constant of the B_s meson and the bottom quark mass in the quenched approximation and continuum limit of lattice QCD. We start from observables in intermediate volume and then estimate the finite volume effects within HQET and QCD, to arrive at the large volume results.
