abstract

At high baryon chemical potential $\mu_B$, the equation of state of QCD allows a weak-coupling expansion in the QCD coupling $\alpha_s$. The result is currently known up to and including the full next-to-next-to-leading order (NNLO) $\alpha_s^2$. Starting at this order, the computations are complicated by the modification of particle propagation in a dense medium, which necessitates non-perturbative treatment of the scale $\alpha_s^{1/2} \mu_B$. In this work, we apply a Hard-Thermal-Loop scheme for capturing the contributions of this scale to the weak-coupling expansion, and use it to determine the leading-logarithm contribution to NNNLO: $\alpha_s^3 \ln^2 \alpha_s$. This result is the first improvement to the equation of state of massless cold quark matter in 40 years. The new term is negligibly small, and thus significantly increases our confidence in the applicability of the weak-coupling expansion.

  2. Renormalizing the Quark-Meson-Diquark Model

    hep-ph 2025-05 conditional novelty 6.0 of 10

    Renormalized and two RG-consistent versions of the Quark-Meson-Diquark model reproduce the BCS relation and Stefan-Boltzmann limit at high density, while the sigma-delta scheme violates the BCS relation.

    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.
