Universal properties of bulk viscosity near the QCD phase transition
F. Karsch, D. Kharzeev, K. Tuchin
We extract the bulk viscosity of hot quark-gluon matter in the presence of light quarks from the recent lattice data on the QCD equation of state. For that purpose we extend the su…
Recent lattice results on finite temperature and density QCD, part I
Frithjof Karsch
We discuss recent progress made studies of bulk thermodynamics of strongly interacting matter through lattice simulations of QCD with an almost physical light and strange quark mas…
Heavy quark free energies for three quark systems at finite temperature
K. Huebner, F. Karsch, O. Kaczmarek +1
We study the free energy of static three quark systems in singlet, octet, decuplet and average color channels in the quenched approximation and in 2-flavor QCD at finite temperatur…
Spectral Properties of Quarks in the Quark-Gluon Plasma
Frithjof Karsch, Masakiyo Kitazawa
We analyze the spectral properties of the quark propagator above the critical temperature for the deconfinement phase transition in quenched lattice QCD using clover improved Wilso…
The QCD Equation of State with almost Physical Quark Masses
M. Cheng, N. H. Christ, S. Datta +12
We present results on the equation of state in QCD with two light quark flavors and a heavier strange quark. Calculations with improved staggered fermions have been performed on la…
Spectral properties of quarks above T_c in quenched lattice QCD
Frithjof Karsch, Masakiyo Kitazawa
We analyze the quark spectral function above the critical temperature for deconfinement in quenched lattice QCD using clover improved Wilson fermions in Landau gauge. We show that…
Color Screening and Quark-Quark Interactions in Finite Temperature QCD
M. Döring, K. Hübner, O. Kaczmarek +1
We analyze the screening of static diquark sources in 2-flavor QCD and compare results with the screening of static quark-antiquark pairs. We show that a two quark system in a fixe…
Transition temperature in QCD with physical light and strange quark masses
Frithjof Karsch
We present results from a calculation of the transition temperature in QCD with two light and one heavier (strange) quark mass on lattices with temporal extent N_t =4 and 6. Calcul…
