Alpha_S from Upsilon Spectroscopy with Dynamical Wilson Fermions
SESAM Collaboration, A. Spitz, H. Hoeber +7
We estimate the QCD coupling constant from a lattice calculation of the bottomonium spectrum. The second order perturbative expansion of the plaquette expectation value is employed…
Flavor Singlet Axial Vector Coupling of the Proton with Dynamical Wilson Fermions
S. Güsken, P. Ueberholz, J. Viehoff +5
We present the results of a full QCD lattice calculation of the flavor singlet axial vector coupling of the proton. The simulation has been carried out on a …
An Estimate of alpha_S from Bottomonium in Unquenched QCD
SESAM Collaboration, A. Spitz, N. Eicker +8
We estimate the strong coupling constant from the perturbative expansion of the plaquette. The scale is set by the 2S-1S and 1P-1S splittings in bottomonium which are computed in N…
Decorrelating Topology with HMC
Th. Lippert, B. Alles, G. Bali +9
The investigation of the decorrelation efficiency of the HMC algorithm with respect to vacuum topology is a prerequisite for trustworthy full QCD simulations, in particular for the…
The Pion-Nucleon sigma-Term with Dynamical Wilson Fermions
SESAM-Collaboration, :, S. Güsken +8
We calculate connected and disconnected contributions to the flavour singlet scalar density amplitude of the nucleon in a full QCD lattice simulation with dynamical Wilson…
Light and Strange Hadron Spectroscopy with Dynamical Wilson Fermions
N. Eicker, U. Glässner, S. Güsken +8
We present the final analysis of the light and strange hadron spectra from a full QCD lattice simulation with two degenerate dynamical sea quark flavours at on a $16^3 \ti…
