Tempered Fermions in the Hybrid Monte Carlo Algorithm
G. Boyd
Parallel tempering simulates at many quark masses simultaneously, by changing the mass during the simulation while remaining in equilibrium. The algorithm is faster than pure HMC i…
Topology in QCD
G. Boyd, B. Alles, M. D'Elia +1
Topology on the lattice is reviewed. In quenched QCD topological susceptibility chi is fully understood. The Witten-Veneziano mechanism for the eta' mass is confirmed. The topologi…
The spin content of the proton in full QCD
B. Alles, G. Boyd, M. D'Elia +1
We present preliminary results on the proton spin structure function in full QCD. The measurement has been done using 4 flavours of staggered fermions and an improved definition of…
Hadron spectroscopy and static quark potential in full QCD: A comparison of improved actions on the CP-PACS
PACS Collaboration, S. Aoki, G. Boyd +10
We present first results from a full QCD calculation on the CP-PACS, comparing various actions at and --0.9. We use the plaquette and a reno…
CP-PACS results for quenched QCD spectrum with the Wilson action
S. Aoki, G. Boyd, R. Burkhalter +8
We present progress report of a CP-PACS calculation of quenched QCD spectrum with the Wilson quark action. Light hadron masses and meson decay constants are obtained at 5.9, 6.…
CP-PACS Result for the Quenched Light Hadron Spectrum
PACS Collaboration, S. Aoki, G. Boyd +9
The quenched hadron spectrum in the continuum obtained with the Wilson quark action in recent simulations on the CP-PACS is presented. Results for the light quark masses and the QC…
