The pressure and the energy density of the SU(3) gauge theory are calculated on lattices with temporal extent N τ = 4, 6 and 8 and spatial extent N σ = 16 and 32. The results are then extrapolated to the continuum limit. In the investigated temperature range up to five times T c we observe a 15% deviation from the ideal gas limit. We also present new… (More)

We calculate the pressure in QCD with two and three light quarks on a lattice of size 16 3 × 4 using tree level improved gauge and fermion actions. We argue that for temperatures T > ∼ 2T c systematic effects due to the finite lattice cutoff and non-vanishing quark masses are below 15% in this calculation and give an estimate for the continuum extrapolated… (More)

We analyze the quark mass and flavour dependence of the QCD phase transition temperature. When the lightest pseudo-scalar meson mass (m PS) is larger than 2 GeV the critical temperature is controlled by the gluonic sector of QCD alone. For smaller values of the lightest meson mass the pseudo-critical temperature decreases slowly with m PS. For a large… (More)

Heavy quark potentials are investigated at high temperatures. The temperature range covered by the analysis extends from T values just below the deconfinement temperature up to about 4T c in the deconfined phase. We simulated the pure gauge sector of QCD on lattices with temporal extents of 4, 6 and 8 with spatial volumes of 32 3. On the smallest lattice a… (More)

The separation of a heavy quark and antiquark pair leads to the formation of a tube of flux, or string, which should break in the presence of light quark-antiquark pairs. This expected zero temperature phenomenon has proven elusive in simulations of lattice QCD. We present simulation results that show that the string does break in the confining phase at… (More)

We calculate the string tension, deconfinement transition temperature and bulk thermodynamic quantities of the SU(3) gauge theory using tree level and tadpole improved actions. Finite temperature calculations have been performed on lattices with temporal extent N τ = 3 and 4. Compared to calculations with the standard Wilson action on this size lattices we… (More)

The status of lattice QCD investigations at high temperature is reviewed. After a short introduction into thermal QCD on the lattice we report on the present understanding of the phase diagram and the equation of state, in particular in presence of dynamical quarks. We continue with a discussion of various screening lengths in the plasma phase including… (More)

We determine the second order endpoint of the line of first order phase transitions, which occur in the light quark mass regime of 3-flavour QCD at finite temperature, and analyze universal properties of this chiral critical point. A detailed analysis of Binder cumulants and the joint probability distributions of energy like and ordering-field like… (More)

Through a detailed investigation of the SU(3) gauge theory at finite temperature on lattices of various size we can control finite lattice cutoff effects in bulk ther-modynamic quantities. We calculate the pressure and energy density of the SU(3) gauge theory on lattices with temporal extent N τ = 4, 6 and 8 and spatial extent N σ = 16 and 32. The results… (More)
