چکیده
We present numerical results on the static quark–anti-quark grand canonical potential in full QCD at non-vanishing temperature (T) and quark chemical potential (µ). Non-zero µ-s are reached by means of multi-parameter reweighting. The dynamical staggered simulations were carried out for n f = 2 + 1 flavors with physical quark masses on 4 × 12 3 lattices.

We report on the first large-scale study of two flavor QCD with domain wall fermions (DWF). Simulation has been carried out at three dynamical quark mass values about 1/2, 3/4, and 1 mstrange on 16 3 × 32 volume with Ls = 12 and a −1 ≈ 1.7 GeV. After discussing the details of the simulation, we report on the light hadron spectrum and decay constants.

We perform an investigation of the static quark-quark-potential both in the confined and the de-confined phase. We discuss conceptual and technical problems and present first results of an exploratory numerical investigation. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

We report on our study of QCD thermodynamics with 2 + 1 flavors of dynamical quarks. In this proceeding we present several thermodynamic quantities and our recent calculation of the critical temperature. In order to investigate the thermodynamic properties of QCD near the continuum limit we adopt improved staggered (p4) quarks coupled with tree-level Symanzik improved glue on Nt = 4 and 6 latti...

We review the overlap pathology of the Glasgow reweighting method for finite density QCD, and discuss the sampling bias that effects the determination of the ensemble-averaged fugacity polynomial expansion coefficients that form the Grand Canonical Partition function. The expectation of the difference in free energies between canonical partition functions generated with different measures is pr...
