Quarkonium spectral functions with complex potential
C. Miao, A. Mocsy, P. Petreczky
We study quarkonium spectral functions at high temperatures using potential model with complex potential. The real part of the potential is constrained by the lattice QCD data on s…
Progress in Lattice QCD at non-zero temperature and QGP
P. Petreczky
I review recent progress in lattice QCD at non-zero temperature whith emphasis on the calculations of equation and the deconfinement as well as the chiral aspects of the QCD transi…
Taste symmetry and QCD thermodynamics with improved staggered fermions
Alexei Bazavov, Peter Petreczky
Taste symmetry violations in staggered fermion formulations correlate strongly with the cut-off (lattice spacing) dependence in thermodynamic quantities. Better taste symmetry on t…
The phase boundary for the chiral transition in (2+1)-flavor QCD at small values of the chemical potential
O. Kaczmarek, F. Karsch, E. Laermann +6
We determine the chiral phase transition line in (2+1)-flavor QCD for small values of the light quark chemical potential. We show that for small values of the chemical potential th…
Heavy quarkonium: progress, puzzles, and opportunities
N. Brambilla, S. Eidelman, B. K. Heltsley +64
A golden age for heavy quarkonium physics dawned a decade ago, initiated by the confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of related experime…
Meson screening masses from lattice QCD with two light and the strange quark
M. Cheng, S. Datta, A. Francis +12
We present results for screening masses of mesons built from light and strange quarks in the temperature range of approximately between 140 MeV to 800 MeV. The lattice computations…
QCD at non-zero temperature: bulk properties and heavy quarks
P. Petreczky
I review recent progress in lattice QCD at non-zero temperature whith emphasis on the calculations of equation of state and the properties of heavy quar anti-quark pairs at high te…
Chiral transition and deconfinement transition in QCD with the highly improved staggered quark (HISQ) action
A. Bazavov, P. Petreczky
We report preliminary results on the chiral and deconfinement aspects of the QCD transition at finite temperature using the Highly Improved Staggered Quark (HISQ) action on lattice…
Polyakov loop and correlator of Polyakov loops at next-to-next-to-leading order
Nora Brambilla, Jacopo Ghiglieri, Peter Petreczky +1
We study the Polyakov loop and the correlator of two Polyakov loops at finite temperature in the weak-coupling regime. We calculate the Polyakov loop at order g^4. The calculation…

Alexei Bazavov, Peter Petreczky
We report on investigations of the chiral and deconfinement aspects of the finite temperature transition in 2+1 flavor QCD using the Highly Improved Staggered Quark (HISQ) action o…
On Fluctuations of Conserved Charges : Lattice Results Versus Hadron Resonance Gas
Pasi Huovinen, Peter Petreczky
We compare recent lattice results on fluctuations and correlations of strangeness, baryon number and electric charge obtained with p4 improved staggered action with the prediction…
