The third moments of conserved charges, the baryon and electric charge numbers, and energy, as well as their mixed moments, carry more information on the state around the QCD phase boundary than previously proposed fluctuation observables and higher order moments. In particular, their signs give plenty of information on the location of the state created in relativistic heavy ion collisions in the temperature and baryon chemical potential plane. We demonstrate this with an effective model.

    In the trivirial model, cluster expansion coefficients b_k have asymptotics b_k ~ A e^{-k μ_R/T} k^{-α} sin(...), switching behavior at the critical temperature, and fitting the first four coefficients to lattice data...

  3. Flavor-Dependent QCD Critical Endpoint and Dual-Channel Fluctuations from Multi-Charge Holography

    hep-ph 2026-07 conditional novelty 6.0 of 10

    A multi-charge holographic QCD model predicts coherent baryon- and charge-fluctuation peaks at sqrt(s_NN) ≈ 5-7 GeV, marking the QCD critical endpoint.

  4. Cumulant dynamics in finite-memory diffusion

    hep-th 2026-06 unverdicted novelty 6.0 of 10

    Finite current relaxation introduces memory effects that suppress, shift, and reshape non-monotonic cumulant behavior relative to instantaneous equilibrium and Fickian diffusion, most visibly in higher-order cumulants.

  5. Phase transition of hot dense QCD Matter from a refined holographic EMD model

    hep-ph 2025-07 conditional novelty 4.0 of 10

    A holographic EMD model calibrated to lattice QCD predicts a kappa sigma squared peak at 3 to 5 GeV in heavy-ion collisions, provided the chemical freeze-out curve avoids the first-order transition line.

    Recent net-proton cumulant ratios from RHIC BES-II data are compared to non-critical models from Lattice QCD, HRG, hydrodynamics and UrQMD, with volume fluctuation effects noted at fixed-target energies.
