Flavour singlet pseudoscalar masses in N_f = 2 QCD
T. Struckmann, K. Schilling, G. Bali +8
We perform a lattice mass analysis in the flavour singlet pseudoscalar channel on the SESAM and TXL full QCD vacuum configurations, with 2 active flavours of dynamical Wilson fermi…
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 …
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…
Critical Dynamics of the Hybrid Monte Carlo Algorithm
SESAM, TXL collaboration, : +13
We investigate the critical dynamics of the Hybrid Monte Carlo algorithm approaching the chiral limit of standard Wilson fermions. Our observations are based on time series of leng…
