Query: B-physics with $N_f=2$ Wilson fermions   We report the final results of the ALPHA collaboration for some B-physics
observables: $f_B$, $f_{B_s}$ and $m_b$. We employ CLS configurations with 2
flavors of $O(a)$ improved Wilson fermions in the sea and pion masses ranging
down to 190 MeV. The b-quark is treated in HQET to order $1/m_b$. The
renormalization, the matching and the improvement were performed
non-perturbatively, and three lattice spacings reaching $a=0.048$ fm are used
in the continuum extrapolation.
