The flavour and quark mass dependence of thermodynamic quantities in lattice QCD
F. Karsch, E. Laermann, A. Peikert
The dependence of thermodynamic properties of QCD on the number of quark flavours is investigated. Lattice results for the equation of state are presented for 2, 2+1 and 3 quark fl…
Further Evidence for an unstable H-Dibaryon?
I. Wetzorke, F. Karsch, E. Laermann
We present preliminary results for the mass of the 6q flavor-singlet state (, ) called H-dibaryon, calculated in quenched QCD on x30 and x30 lattices wit…
The non-zero baryon number formulation of QCD
O. Kaczmarek with J. Engels, F. Karsch, E. Laermann
We discuss the non-zero baryon number formulation of QCD in the quenched limit at finite temperature. This describes the thermodynamics of gluons in the background of static quark…
Heavy Quark Potentials in Quenched QCD at High Temperature
Olaf Kaczmarek, Frithjof Karsch, Edwin Laermann +1
Heavy quark potentials are investigated at high temperatures. The temperature range covered by the analysis extends from values just below the deconfinement temperature up to a…
Lattice QCD at non-zero baryon number
O. Kaczmarek, with J. Engels, F. Karsch +1
We discuss the quenched limit of lattice QCD at non-zero baryon number density. We find evidence for a mixed phase that becomes broader with increasing baryon number. Although the…
The Phase Diagram of 2 flavour QCD with improved Actions
F. Karsch, E. Laermann, M. Oevers +1
It has been proposed, that the chiral continuum limit of 2-flavour QCD with Wilson fermions is brought about by a phase in which flavour and parity symmetry are broken spontaneousl…
The quenched limit of lattice QCD at non-zero baryon number
J. Engels, O. Kaczmarek, F. Karsch +1
We discuss the thermodynamics of gluons in the background of static quark sources. In order to do so we formulate the quenched limit of QCD at non-zero baryon number. A first numer…
The three flavour chiral phase transition with an improved quark and gluon action in lattice QCD
F. Karsch, E. Laermann, A. Peikert +1
The finite-temperature chiral phase transition is investigated for three flavours of staggered quarks on a lattice of temporal extent N_t=4. In the simulation we use an improved fe…
