Static quark correlators and quarkonium properties at non-zero temperature
A. Bazavov, P. Petreczky
We discuss different static quark correlators, including Wilson loops in 2+1 flavor QCD at non-zero temperature and their relation to in-medium quarkonium properties. We present la…
On trace anomaly in 2+1 flavor QCD
P. Petreczky
We report on recent progress by the HotQCD collaboration in studying the trace anomaly at non-zero temperature in 2+1 flavor QCD on lattices with the temporal extent N_tau=4, 6, 8,…
On static quark anti-quark potential at non-zero temperature
A. Bazavov, P. Petreczky
We study Wilson loops at non-zero temperature and extract the static quark potential from them. The extracted potentials are larger than the singlet free energies and do not show s…
Freeze-out Conditions in Heavy Ion Collisions from QCD Thermodynamics
A. Bazavov, H. -T. Ding, P. Hegde +9
We present a determination of chemical freeze-out conditions in heavy ion collisions based on ratios of cumulants of net electric charge fluctuations. These ratios can reliably be…
The chiral transition and U(1)_A symmetry restoration from lattice QCD using Domain Wall Fermions
HotQCD Collaboration, A. Bazavov, Tanmoy Bhattacharya +15
We present results on both the restoration of the spontaneously broken chiral symmetry and the effective restoration of the anomalously broken U(1)_A symmetry in finite temperature…
Determination of alpha_s from the QCD static energy
Alexei Bazavov, Nora Brambilla, Xavier Garcia i Tormo +3
We compare lattice data for the short-distance part of the static energy in 2+1 flavor quantum chromodynamics (QCD) with perturbative calculations, up to next-to-next-to-next-to le…
Numerical study of hot strongly interacting matter
P. Petreczky
I review recent progress in study of strongly interacting matter at high temperatures using Monte-Carlo simulations in lattice QCD.
Lattice QCD at non-zero temperature
P. Petreczky
I review our current understanding of the properties of strongly interacting matter at high temperatures, based upon numerical calculations in lattice QCD. I discuss the chiral and…
Signatures of charmonium modification in spatial correlation functions
F. Karsch, E. Laermann, Swagato Mukherjee +1
We study spatial correlation functions of charmonium in 2+1 flavor QCD using an improved staggered formulation. Contrary to the temporal correlation functions the spatial correlati…
Fluctuations and Correlations of net baryon number, electric charge, and strangeness: A comparison of lattice QCD results with the hadron resonance gas model
A. Bazavov, Tanmoy Bhattacharya, C. E. DeTar +15
We calculate the quadratic fluctuations of net baryon number, electric charge and strangeness as well as correlations among these conserved charges in (2+1)-flavor lattice QCD at z…
Equation of state in 2+1 flavor QCD with improved Wilson quarks by the fixed scale approach
T. Umeda, S. Aoki, S. Ejiri +4
We study the equation of state in 2+1 flavor QCD with nonperturbatively improved Wilson quarks coupled with the RG-improved Iwasaki glue. We apply the -integration method to non…
Equation of state at non-zero baryon density based on lattice QCD
Pasi Huovinen, Peter Petreczky, Christian Schmidt
We employ the lattice QCD data on Taylor expansion coefficients to extend our previous parametrization of the equation of state to finite baryon density. When we take into account…
