One is a cutoff effect, others concern thecontribution of multi-pion states to correlation functions and are expected to survive the contin-uum limit. We then turn to the preparation for simulations at small lattice spacings which weare planning down to around a = 0:04 fm in order to understand the size of O(a

Scaling test of two-flavor O(a)-improved lattice QCD
We report on a scaling test of several mesonic observables in the non-perturbatively O(a) improved Wilson theory with two flavors of dynamical quarks. The observables are constructed in a fixed
Heavy-light decay constant at the 1/m order of HQET
Following the strategy developed by the ALPHA collaboration, we present a method to compute non-perturbatively the decay constant of a heavy-light meson in HQET including the 1/m corrections. We
Non-perturbative improvement of quark mass renormalization in two-avour
We non-perturbatively determine the renormalization constant and the im- provement coecients relating the renormalized current and subtracted quark mass in O( a) improved two-avour lattice QCD. We
Towards a non-perturbative matching of HQET and QCD with dynamical light quarks ∗
We explain how the strategy of solving renormalization problems in HQET non-perturbatively by a matching to QCD in finite volume can be implemented to includ e dynamical fermions. As a primary
Non-perturbative improvement of quark mass renormalization in two-flavour lattice QCD
We non-perturbatively determine the renormalization constant and the improvement coefficients relating the renormalized current and subtracted quark mass of (quenched) valence quarks propagating in a
Investigating the critical slowing down of QCD simulations
Simulations of QCD are known to suffer from serious critical slowing down towards the continuum limit. This is particularly prominent in the topological charge. We investigate the severeness of the
Ds physics from fine lattices
We present a preliminary analysis of the charm quark mass and the mass and decay constant fDs of the Ds meson obtained from dynamical simulations of Nf = 2 Wilson QCD on the large and fine lattices

We introduce new discretizations of the action for static quarks. They achieve an exponential improvement (compared to the Eichten-Hill regularization) on the signal to noise ratio in static-light
