abstract

We calculate the Equation of State at high temperatures in 2+1 flavor QCD using the highly improved staggered quark action. We study the lattice spacing dependence of the pressure at high temperatures using lattices with temporal extent $N_{\tau}=6,~8,~10$ and $12$ and perform continuum extrapolations. We also give a continuum estimate for the Equation of State up to temperatures $T=2$ GeV, which are then compared with results of the weak-coupling calculations. We find a reasonably good agreement with the weak-coupling calculations at the highest temperatures.

  1. The Equation of State of QCD up to very high temperatures

    hep-lat 2025-02 conditional novelty 7.0 of 10

    Using shifted boundary conditions, the authors compute s/T^3 in Nf=3 QCD from 3 to 165 GeV and find values a few percent below the Stefan-Boltzmann limit.

  2. Analytic structure of stress-energy response functions and new Kubo formulae

    hep-ph 2025-07 unverdicted novelty 6.0 of 10

    Authors derive new Kubo formulae for transport coefficients by analyzing analytic structures of stress-energy response functions in second- and third-order hydrodynamics.

  3. Quarkyonic picture of isospin QCD

    nucl-th 2025-05 conditional novelty 6.0 of 10

    Cold isospin QCD is modeled as a pion condensate plus free quarks, with a quarkyonic onset near 0.23 fm^-3 and high-density pion dissociation toward the conformal limit.

  4. In-medium bottomonium properties from lattice NRQCD calculations with extended meson operators

    hep-lat 2025-01 conditional novelty 6.0 of 10

    Bottomonium masses do not shift in the quark-gluon plasma up to 250 MeV, but thermal widths are nonzero and highly sensitive to the assumed spectral function shape.

  5. One-loop HDL thermodynamics of a strongly magnetized isospin asymmetric cold quark matter

    hep-ph 2026-07 conditional novelty 5.0 of 10

    In the lowest Landau level, one-loop HDLpt pressure of cold quark matter grows with quark and isospin chemical potentials, and the magnetization is positive, making transverse pressure smaller than longitudinal.

  6. The determination of potential scales in 2+1 flavor QCD

    hep-lat 2024-12 conditional novelty 5.0 of 10

    A new lattice QCD determination of the hadronic scales r0 = 0.4729(75) fm and r1 = 0.3127(40) fm in 2+1 flavor QCD, together with r0 Λ_MSbar^(3) = 0.820(28).
