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…
Faster Fermions in the Tempered Hybrid Monte Carlo Algorithm
G. Boyd
Tempering is used to change the quark mass while remaining in equilibrium between the trajectories of a standard hybrid Monte Carlo simulation of four flavours of staggered fermion…
New results on topological susceptibility in SU(3) gauge theory
B. Alles, G. Boyd, M. D'Elia +1
We survey recent lattice results on QCD topological properties. The behaviour of the topological susceptibility at the deconfining phase transition has been determined. This advanc…
Two Flavour QCD Phase Transition
G. Boyd, F. Karsch, E. Laermann +1
Results on the phase transition in QCD with two flavours of light staggered fermions from an ongoing simulation are presented. We find the restoration of the chiral SU(2) x SU(2) s…
