Towards a non-perturbative computation of the RGI strange quark mass with two dynamical flavors
Michele Della Morte, Roland Hoffmann, Francesco Knechtli +4
The non-perturbative running of the quark mass in the Schroedinger functional scheme is computed over a large energy range (covering scales differing by two orders of magnitude). T…
Computation of the strong coupling in QCD with two dynamical flavours
Michele Della Morte, Roberto Frezzotti, Jochen Heitger +3
We present a non-perturbative computation of the running of the coupling alpha_s in QCD with two flavours of dynamical fermions in the Schroedinger functional scheme. We improve ou…
Large cutoff effects of dynamical Wilson fermions
R. Sommer, S. Aoki, M. Della Morte +6
We present and discuss results for cutoff effects in the PCAC masses and the mass dependence of r_0 for full QCD and various fermion actions. Our discussion of how one computes mas…
Towards a precision computation of f_Bs in quenched QCD
J. Rolf, M. Della Morte, S. Durr +5
We present a computation of the decay constant f_Bs in quenched QCD. Our strategy is to combine new precise data from the static approximation with an interpolation of the decay co…
Non-perturbative renormalization of the axial current with improved Wilson quarks
R. Hoffmann, F. Knechtli, J. Rolf +2
We present a new normalization condition for the axial current, which is derived from the PCAC relation with non-vanishing mass. Using this condition reduces the O(r_0 m) correctio…
A precise determination of the decay constant of the D(s)-meson in quenched QCD
Andreas Juttner, Juri Rolf
We present a precise determination of the leptonic decay constant F_D(s) of the D(s)-meson in quenched lattice QCD. This work is particularly focused on the analysis and discussion…
Lattice HQET with exponentially improved statistical precision
M. Della Morte, S. Durr, J. Heitger +4
We introduce an alternative discretization for static quarks on the lattice retaining the O(a) improvement properties of the Eichten-Hill action. In this formulation, statistical f…
A precise determination of the decay constant of the Ds-meson in quenched QCD
Andreas Juettner, Juri Rolf
We present a lattice determination of the leptonic decay constant F_Ds of the Ds-meson using its mass and F_K as experimental input. Setting the scale with F_K=160 MeV, our final r…
Recent results on the running coupling in QCD with two massless flavours
M. Della Morte, R. Frezzotti, J. Heitger +4
We report on the latest results on the running coupling of two flavour QCD in the Schrödinger functional scheme. Results for the step scaling function are obtained from simulations…
Schrödinger functional at N_f=-2
Bernd Gehrmann, Stefan Kurth, Juri Rolf +1
We study the Schrödinger functional coupling for lattice Yang-Mills theory coupled to an improved bosonic spinor field, which corresponds to QCD with minus two light flavors. This…
Status of APEmille
APE-Collaboration, :, A. Bartoloni +31
This paper presents the status of the APEmille project, which is essentially completed, as far as machine development and construction is concerned. Several large installations of…

Bernd Gehrmann, Juri Rolf, Stefan Kurth +1
The scaling of the Schr"odinger functional coupling is studied numerically and perturbatively for an SU(3) lattice gauge field coupled to an O(a) improved bosonic spinor field. Thi…

Achim Bode, Roberto Frezzotti, Bernd Gehrmann +11
We report on the non-perturbative computation of the running coupling of two-flavour QCD in the Schr"odinger functional scheme. The corresponding Lambda-parameter, which describes…
Non-perturbative results for the coefficients b_m and b_a-b_p in O(a) improved lattice QCD
Marco Guagnelli, Roberto Petronzio, Juri Rolf +3
We determine the improvement coefficients b_m and b_a-bp in quenched lattice QCD for a range of beta-values, which is relevant for current large scale simulations. At fixed beta, t…

A non perturbative finite size scaling technique is used to study a running coupling in lattice Yang-Mills theory coupled to a bosonic Wilson spinor field in the Schrödinger functi…
The Hierarchical - Trajectory by Perturbation Theory in a Running Coupling and its Logarithm
J. Rolf, C. Wieczerkowski
We compute the hierarchical -trajectory in terms of perturbation theory in a running coupling. In the three dimensional case we resolve a singularity due to resonance of power…
