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 \t…
transition form factors in Quenched and QCD
C. Alexandrou, Ph. de Forcrand, Th. Lippert +5
Calculations of the magnetic dipole, electric quadrupole and Coulomb quadrupole amplitudes for the transition are presented both in quenched QCD and with two flavours o…
Improving the dynamical overlap algorithm
N. Cundy, S. Krieg, Th. Lippert
We present algorithmic improvements to the overlap Hybrid Monte Carlo algorithm, including preconditioning techniques and improvements to the correction step, used when one of the…
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…
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…
Finite size scaling analysis of compact QED
G. Arnold, Th. Lippert, Th. Neuhaus +1
We describe results of a high-statistics finite size scaling analysis of 4d compact U(1) lattice gauge theory with Wilson action at the phase transition point. Using a multicanonic…
