U_A(1) breaking at finite temperature from the Dirac spectrum with the dynamical HISQ action
H. Ohno, U. M. Heller, F. Karsch +1
We investigate breaking above in terms of the Dirac spectrum on configurations with (2+1)-flavors, using the HISQ action. The strange quark mass is at its physical v…
Charmonium dissociation and heavy quark transport in hot quenched lattice QCD
H. -T. Ding, A. Francis, O. Kaczmarek +3
We study the properties of charmonium states at finite temperature in quenched lattice QCD on large and fine isotropic lattices. We perform a detailed analysis of charmonium correl…
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…
Thermal mass and dispersion relations of quarks in the deconfined phase of quenched QCD
Olaf Kaczmarek, Frithjof Karsch, Masakiyo Kitazawa +1
Temporal quark correlation functions are analyzed in quenched lattice QCD for two values of temperature above the critical temperature (Tc) for deconfinement, T=1.5Tc and 3Tc. A tw…
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…
Charmonium properties in hot quenched lattice QCD
H. -T. Ding, A. Francis, O. Kaczmarek +3
We study the properties of charmonium states at finite temperature in quenched QCD on large and fine isotropic lattices. We perform a detailed analysis of charmonium correlation an…
