The finite temperature phase transition in four flavour QCD on an 8×12 3 lattice
(1989) In Physics Letters B 232(4). p.491-497- Abstract
We present results of a numerical study of lattice QCD with four dynamical flavours of staggered fermions, performed by using a hybrid Monte Carlo algorithm on an 8×12 3 lattice. We find a rapid change in the average value of the Polyakov loop at β c =5.25±0.025 for a quark mass ma=0.025; at this mass value, the behaviour of the chiral order parameter, 〈ΨΨ〉 does not yet allow an independent determination of the transition point. Using existing hadron mass calculations, the value of β c we have obtained here would... (More)
We present results of a numerical study of lattice QCD with four dynamical flavours of staggered fermions, performed by using a hybrid Monte Carlo algorithm on an 8×12 3 lattice. We find a rapid change in the average value of the Polyakov loop at β c =5.25±0.025 for a quark mass ma=0.025; at this mass value, the behaviour of the chiral order parameter, 〈ΨΨ〉 does not yet allow an independent determination of the transition point. Using existing hadron mass calculations, the value of β c we have obtained here would lead to a transition temperature T∼100 MeV.
