First results on QCD thermodynamics with HISQ action
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 Equation of State at physical quark masses
P. Petreczky
QCD equation of state is calculated in (2+1) flavor QCD at temperatures corresponding fermion action on lattices with temporal extent . The results are compared with previou…
QCD Equation of State and Hadron Resonance Gas
P. Huovinen, P. Petreczky
We compare the trace anomaly, strangeness and baryon number fluctuations calculated in lattice QCD with expectations based on hadron resonance gas model. We find that there is a si…
Quark number fluctuations at high temperatures
Peter Petreczky, Prasad Hegde, Alexander Velytsky
We calculate the second, fourth and sixth order quark number fluctuations in the deconfined phase of 2+1 flavor QCD using lattices with temporal extent Nt=4, 6, 8 and 12. We consid…
Lattice QCD at finite temperature : present status
P. Petreczky
I review recent progress in finite temperature lattice calculations, including calculations of Equation of State, fluctuations of conserved charges and spatial correlation function…
On the magnetic equation of state in (2+1)-flavor QCD
S. Ejiri, F. Karsch, E. Laermann +6
A first study of critical behavior in the vicinity of the chiral phase transition of (2+1)-flavor QCD is presented. We analyze the quark mass and volume dependence of the chiral co…
Recent progress in lattice QCD at finite temperature
Peter Petreczky
I review recent progress in finite temperature lattice calculations, including the study of the nature of the deconfinement transition in QCD, equation of state, screening of stati…
Quarkonium at Finite Temperature
Alexei Bazavov, Peter Petreczky, Alexander Velytsky
We discuss properties of heavy quarkonium states at high temperatures based on lattice QCD and potential models. We review recent progress made in lattice calculations of spatial s…
Equation of state and QCD transition at finite temperature
A. Bazavov, T. Bhattacharya, M. Cheng +20
We calculate the equation of state in 2+1 flavor QCD at finite temperature with physical strange quark mass and almost physical light quark masses using lattices with temporal exte…
