Free Meson Spectral Functions on the Lattice

S. Stickan, F. Karsch, E. Laermann +1

We present results from an analytic calculation of thermal meson spectral functions in the infinite temperature (free field) limit. We compare spectral functions for various lattic…

Common features of deconfining and chiral critical points in QCD and the three state Potts model in an external field

F. Karsch, Ch. Schmidt, S. Stickan

In the presented study we investigated the second order endpoints of the lines of first order phase transitions which emerge for the QCD in the heavy and light quark mass regime an…

Meson Spectral Functions at finite Temperature

I. Wetzorke, F. Karsch, E. Laermann +2

The Maximum Entropy Method provides a Bayesian approach to reconstruct the spectral functions from discrete points in Euclidean time. The applicability of the approach at finite te…

Temporal quark and gluon propagators: measuring the quasiparticle masses

P. Petreczky, F. Karsch, E. Laermann +2

We calculate the Coulomb gauge temporal quark and gluon propagators in quenched QCD. From the temporal quark and gluon propagators, dispersion relations and quasiparticle masses ar…

A Lattice Calculation of Thermal Dilepton Rates

F. Karsch, E. Laermann, P. Petreczky +2

Using clover improved Wilson fermions we calculate thermal vector meson correlation functions above the deconfinement phase transition of quenched QCD. At temperatures 1.5 Tc and 3…

Lattice calculation of medium effects at short and long distances

P. Petreczky with O. Kaczmarek, F. Karsch, E. Laermann +3

We investigate medium effects in QCD like chromoelectric screening and quasi-particle mass generation by calculating the heavy quark potential as well as the temporal quark and glu…

Flavor and Quark Mass Dependence of QCD Thermodynamics

F. Karsch, E. Laermann, A. Peikert +2

We calculate the transition temperature in 2 and 3-flavor QCD using improved gauge and staggered fermion actions on lattices with temporal extent Nt=4. We find Tc=173(8)MeV and 154…

QCD Thermodynamics with 2 and 3 Quark Flavors

F. Karsch, E. Laermann, A. Peikert +2

We discuss the flavor dependence of the pressure and critical temperature calculated in QCD with 2, 2+1 and 3 flavors using improved gauge and staggered fermion actions on lattices…

The three-dimensional, three-state Potts Model in an External Field

Frithjof Karsch, Sven Stickan

We analyze the critical behaviour of the three-dimensional, three-state Potts model in the presence of an external ordering field. From a finite size scaling analysis on lattices o…
