First Lattice Study of Ghost Propagators in SU(2) and SU(3) Gauge Theories
H. Suman, K. Schilling
We present a numerical study of the ghost propagators in Landau gauge for SU(2) and SU(3) gauge theories at =2.7 and =6.0, respectively. Analyzing different lattice sizes up…
Semileptonic Decays of D and B Mesons
S. Güsken, K. Schilling, G. Siegert
We report results of our ongoing investigation concerning semileptonic decays of heavy pseudoscalar mesons into pseudoscalar and vector mesons. Particular attention is paid to unce…
Weak Decays of Heavy-Light Mesons on the Lattice: Semi-Leptonic Formfactors
S. Güsken, G. Siegert, K. Schilling
We report results (on an intermediate statistics sample) of a study of weak semi-leptonic formfactors of and decays, addressing the uncertainties from mass extrapolations t…
Hyper-Systolic Parallel Computing
Th. Lippert, A. Seyfried, A. Bode +1
A new class of parallel algorithms is introduced that can achieve a complexity of O(n^3/2) with respect to the interprocessor communication, in the exact computation of systems wit…
Quark-Antiquark Forces From SU(2) and SU(3) Gauge Theories on Large Lattices
Gunnar S. Bali, Klaus Schilling, Armin Wachter
We present results on the spin-independent quark-antiquark potential in SU(3) gauge theory from a simulation on a 48^3*64 lattice at Beta = 6.8, corresponding to a volume of (1.7 f…
Many Masses on One Stroke: Economic Computation of Quark Propagators
Andreas Frommer, Stephan Güsken, Thomas Lippert +2
The computational effort in the calculation of Wilson fermion quark propagators in Lattice Quantum Chromodynamics can be considerably reduced by exploiting the Wilson fermion matri…
