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 volume of 2.4fm x (1.8fm)^3 with Schroedinger functional boundary conditions. [...]

Non-perturbative O(a) improvement of lattice QCD
/ Luscher, Martin (DESY) ; Sint, Stefan (Florida State U., SCRI) ; Sommer, Rainer (DESY, Zeuthen ; CERN) ; Weisz, Peter (Munich, Max Planck Inst.) ; Wolff, Ulli (Humboldt U., Berlin)
The coefficients multiplying the counterterms required for O($a$) improvement of the action and the isovector axial current in lattice QCD are computed non-perturbatively, in the quenched approximation and for bare gauge couplings $g_0$ in the range $0 \leq g_0 \leq 1$. A finite-size method based on the Schr\"odinger functional is employed, which enables us to perform all calculations at zero or nearly zero quark mass. [...]

Some new results in O(a) improved lattice QCD
/ Luscher, Martin (DESY) ; Sint, Stefan (Munich, Max Planck Inst.) ; Sommer, Rainer (CERN ; DESY, Zeuthen) ; Weisz, Peter (Munich, Max Planck Inst.) ; Wittig, Hartmut (DESY, Zeuthen ; Julich, NIC) ; Wolff, Ulli (Humboldt U., Berlin)
It is shown how on-shell O(a) improvement can be implemented non-perturbatively in lattice QCD with Wilson quarks. Improvement conditions are obtained by requiring the PCAC relation to hold exactly in certain matrix elements. [...]

Non-perturbative renormalization of lattice QCD at all scales
/ Jansen, Karl (DESY) ; Liu, Chuan (DESY) ; Luscher, Martin (DESY) ; Simma, Hubert (Edinburgh U.) ; Sint, Stefan (Munich, Max Planck Inst.) ; Sommer, Rainer (CERN) ; Weisz, Peter (Munich, Max Planck Inst.) ; Wolff, Ulli (Humboldt U., Berlin)
A general strategy to solve the non-perturbative renormalization problem in lattice QCD, using finite-size techniques and numerical simulations, is described. As an illustration we discuss the computation of the axial current normalization constant, the running coupling at zero quark masses and the scale evolution of the renormalized axial density. [...]
