The isentropic equation of state of 2-flavor QCD
S. Ejiri, F. Karsch, E. Laermann +1
Using Taylor expansions of the pressure obtained previously in studies of 2-flavor QCD at non-zero chemical potential we calculate expansion coefficients for the energy and entropy…
Hadronic fluctuations in the QGP
F. Karsch, S. Ejiri, K. Redlich
We analyze fluctuations of quark number and electric charge, in 2-flavour QCD at finite temperature and vanishing net baryon number density. In the hadronic phase we find that an e…
Meson correlation functions at high temperatures
S. Wissel, S. Datta, F. Karsch +2
We present preliminary results for the correlation- and spectral functions of different meson channels on the lattice. The main focus lies on gaining control over cut-off as well a…
The QCD equation of state for two flavours at non-zero chemical potential
S. Ejiri, C. R. Allton, M. Döring +5
We present results of a simulation of 2 flavour QCD on a lattice using p4-improved staggered fermions with bare quark mass . Derivatives of the thermodynamic…
Heavy quark free energies and screening at finite temperature and density
M. Doring, S. Ejiri, O. Kaczmarek +2
We study the free energies of heavy quarks calculated from Polyakov loop correlation functions in full 2-flavour QCD using the p4-improved staggered fermion action. A small but fin…
Hadronic fluctuations at the QCD phase transition
S. Ejiri, F. Karsch, K. Redlich
We discuss the properties of hadronic fluctuations, i.e. fluctuations of net quark and isospin numbers as well as electric charge, in the vicinity of the QCD transition in isospin-…
