The B*Bpi Coupling in the Static Limit
J. Bulava, M. A. Donnellan, Rainer Sommer
We study an accurate method for the lattice calculation of the B*Bpi Coupling in the static limit, paying particular attention to excited state contamination. As this coupling is a…
Running of the SF-coupling with four massless flavours
Rainer Sommer, Fatih Tekin, Ulli Wolff
We discuss the status of different determinations of alpha_s, motivating a precise and reliable computation from lattice QCD. In order to suppress perturbative errors, the non-pert…
On the generalized eigenvalue method for energies and matrix elements in lattice field theory
Benoit Blossier, Michele Della Morte, Georg von Hippel +2
We discuss the generalized eigenvalue problem for computing energies and matrix elements in lattice gauge theory, including effective theories such as HQET. It is analyzed how the…
physics from fine lattices
Georg von Hippel, Rainer Sommer, Jochen Heitger +2
We present a preliminary analysis of the charm quark mass and the mass and decay constant of the meson obtained from dynamical simulations of Wilson QCD o…
On cutoff effects in lattice QCD from short to long distances
Michele Della Morte, Rainer Sommer, Shinji Takeda
We discuss kinematical enhancements of cutoff effects at short and intermediate distances. Starting from a pedagogical example with periodic boundary conditions, we switch to the c…
Scaling test of two-flavor O(a)-improved lattice QCD
Michele Della Morte, Patrick Fritzsch, Harvey B. Meyer +5
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 construct…
