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…
Probing the QCD vacuum with flavour singlet objects: on the lattice
T. Struckmann, K. Schilling, P. Ueberholz +6
We present a study on the direct determination of the mass on the full set of SESAM and TL QCD vacuum configurations with 2 active flavours of Wilson fermions, at .…
Static potentials and glueball masses from QCD simulations with Wilson sea quarks
Gunnar S. Bali, Bram Bolder, Norbert Eicker +5
We calculate glueball and torelon masses as well as the lowest lying hybrid potential in addition to the static ground state potential in lattice simulations of QCD with two flavou…
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…

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 …
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…

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…
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…
