abstract

Fluctuations play a key role in the study of QCD phases. Lattice QCD is a valuable tool to calculate them, but going to high orders is challenging. Up to the fourth order, continuum results are available since 2015. We present the first continuum results for sixth order baryon fluctuations for temperatures between $T=130 - 200$ MeV, and eighth order at $T=145$ MeV in a fixed volume. We show that for $T \leq 145$ MeV, relevant for criticality search, finite volume effects are under control. Our results are in sharp contrast with well known results in the literature obtained at finite lattice spacing.

  1. High-precision baryon number cumulants from lattice QCD in a finite box: cumulant ratios, Lee-Yang zeros and critical endpoint predictions

    hep-lat 2025-07 conditional novelty 6.0 of 10

    High-statistics lattice QCD data up to tenth order, analyzed with a Roberge-Weiss-symmetric rational ansatz, place an 84% upper bound of 103 MeV on the QCD critical endpoint temperature.

  2. Parallel Tempered Metadynamics for full QCD

    hep-lat 2026-07 conditional novelty 5.0 of 10

    In N_f=2 staggered QCD at beta=1.15, PT-MetaD tunnels between topological sectors while RHMC remains frozen, yielding chi_top V = 0.127(33).

  3. Topological Uncertainty for Anomaly Detection in the Neural-network EoS Inference with Neutron Star Data

    nucl-th 2025-08 conditional novelty 4.0 of 10

    Applying Topological Uncertainty to hidden-layer activations of a trained FNN detects failed neutron-star EoS inferences with over 90% success in the best-tested configuration.
