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…
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…
Scanning the Topological Sectors of the QCD Vacuum with Hybrid Monte Carlo
B. Alles, G. Bali, M. D'Elia +10
We address a long standing issue and determine the decorrelation efficiency of the Hybrid Monte Carlo algorithm (HMC), for full QCD with Wilson fermions, with respect to vacuum top…
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…
Improving Stochastic Estimator Techniques for Disconnected Diagrams
J. Viehoff, N. Eicker, S. Guesken +7
Disconnected diagrams are expected to be sensitive to the inclusion of dynamical fermions. We present a feasibility study for the observation of such effects on the nucleonic matri…
Glueballs and string breaking from full QCD
TchiL collaboration, G. S. Bali, N. Eicker +14
We present results on the static potential, and torelon and glueball masses from simulations of QCD with two flavours of dynamical Wilson fermions on and $24^3\time…
