Book Description
Lattice QCD with 2 light staggered quark flavours is being simulated on a 163 x 8 lattice to study the transition from hadronic matter to a quark gluon plasma. We have completed runs at m{sub q} = 0.0125 and are extending this to m{sub q} = 0.00625. We also examine the addition of a non-dynamical strange'' quark. Thermodynamic order parameters are being measured across the transition and further into the plasma phase, as are various screening lengths. No evidence for a first order transition is seen, and we estimate the transition temperature to be {Tc} = 143(7)MeV.

Lattice 91
Author: M. Fukugita
Publisher: Elsevier
ISBN: 1483278050
Category : Science
Languages : en
Pages : 699
Book Description
Lattice 91 covers the proceedings of the International Symposium on Lattice Field Theory held in Tsukuba, Japan on 5-9 November 1991. The book focuses on quantum chromodynamics, Higgs-fermion theories, QED, lattice quantum gravity and random surfaces, spin systems related to field theory, simulation algorithms, and dedicated computers. The selection first offers information on the QCD spectrum and phase diagram on the lattice and QCD at finite density, including phase structure of QCD, Monte-Carlo simulations with dynamical fermions, and quenched approximation. The book then tackles weak matrix elements, simulation of heavy quarks, and sphaleron induced baryon number non-conservation. The text reviews quantum gravity and random surfaces, recent analytic progress in finite size effects, and parallel QCD machines. Discussions focus on two-dimensional quantum gravity, signatures of resonance in finite volume, first order transitions, and determination of the running coupling. The publication also ponders on hadronic forces from the lattice, universality of the confinement string in multiple potentials, and confinement and saddle-point configurations. The selection is highly recommended for readers interested in the lattice field theory.

Book Description
The HTMCGC collaboration has been simulating lattice QCD with two light staggered quarks with masses m{sub q} = 0.0125 and also m{sub q} = 0.00625 on a 163 × 8 lattice. We have been studying the behavior of the transition from hadronic matter to a quark-gluon plasma and the properties of that plasma. We have been measuring entropy densities, Debye and hadronic screening lengths, the spacial string tension and topological susceptibility in addition to the standard order parameters. The HEMCGC collaboration has simulated lattice QCD with two light staggered quarks, m{sub q} = 0.025 and m{sub q} = 0.010 on a 163 × 32 lattice. We have measured the glueball spectrum and topological susceptibilities for these runs.

Book Description
Simulations of Lattice QCD with 4 flavors of light staggered quarks (m = .025) were performed on a 123 x 4 lattice, confirming the first order nature of the transition. Lattice QCD with a light isodoublet of staggered quarks (m = .0125), and a heavier singlet (m = .25) was studied, also on a 123 x 4 lattice. The order of the transition was less clear. Improved glueball wavefunctions have been used to study glueball spectra in theories incorporating dynamical quarks. 10 refs., 3 figs.
