QCD with 2 light quark flavours: Thermodynamics on a 16(sup 3) (times) 8 lattice and glueballs and topological charge on a 16(sup 3) (times) 32 lattice

摘要

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 16(sup 3) (times) 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 16(sup 3) (times) 32 lattice. We have measured the glueball spectrum and topological susceptibilities for these runs.
