Abstract

We report on a study of QCD thermodynamics with three flavors of quarks, using a Symanzik improved gauge action and the Asqtad $O({a}^{2})$ improved staggered quark action. Simulations were carried out with lattice spacings $1/4T$, $1/6T$, and $1/8T$ both for three degenerate quarks with masses less than or equal to the strange quark mass ${m}_{s}$ and for degenerate up and down quarks with masses in the range $0.1{m}_{s}\ensuremath{\le}{m}_{u,d}\ensuremath{\le}0.6{m}_{s}$ and the strange quark mass fixed near its physical value. We present results for standard thermodynamics quantities, such as the Polyakov loop, the chiral order parameter and its susceptibility. For the quark masses studied to date we find a rapid crossover rather than a bona fide phase transition. We have carried out the first calculations of quark number susceptibilities with three flavors of sea quarks. These quantities are of physical interest because they are related to event-by-event fluctuations in heavy ion collision experiments. Comparison of susceptibilities at different lattice spacings show that our results are close to the continuum values.

  • In the quenched approximation on the lattice, the latent heat was determined to be l ≈ 1.4 Tc^4, which is a factor of 5 smaller than expected from a quenched bag model.

    “In the quenched approximation on the lattice, the latent heat was determined to be l ≈ 1 . 4 T 4 c [77, 78], which is a factor of 5 smaller than expected from a quenched bag model.”

    From Phase Transitions in the Early and Present Universe (2006) · cites this paper as [78]

    Sections III (p. 7) and IV (p. 9) describe simulations with three quark flavors, not a quenched lattice calculation. Searches for quenched latent heat, 1.4 Tc^4, and the bag-model comparison found no passage in our copy addressing the claimed value or factor of five. (LLM, conf=0.76)

    Experimental — accuracy not yet measured

  • For the surface tension rather small values are found from quenched lattice QCD, σ ≈ 0.015 Tc^3.

    “For the surface tension rather small values are found from quenched lattice QCD, σ ≈ 0 . 015 T 3 c [78, 82].”

    From Phase Transitions in the Early and Present Universe (2006) · cites this paper as [78]

    The Abstract (p. 2) describes simulations with three flavors of quarks, and the Conclusion (p. 13) reports a transition temperature and quark-number susceptibilities. Searches for surface tension, the value 0.015 Tc³, and quenched-QCD interface tension found no passage in our copy addressing the claimed result. (LLM, conf=0.77)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
