abstract

Based on lattice QCD results of equation of state (EOS) and baryon number susceptibility at zero baryon chemical potential, and supplemented by machine learning techniques, we construct the analytic form of the holographic black hole metric in the Einstein-Maxwell-Dilaton (EMD) framework for pure gluon, 2-flavor, and 2+1-flavor systems, respectively. The dilaton potentials solved from Einstein equations are in good agreement with the extended non-conformal DeWolfe-Gubser-Rosen (DGR) type dilaton potentials fixed by lattice QCD EOS, which indicates the robustness of the EMD framework. The predicted critical endpoint (CEP) in the 2+1-flavor system is located at $(T^c$=0.094GeV, $\mu^c_B$=0.74GeV), which is close to the results from the realistic Polyakov-Nambu-Jona-Lasinio(PNJL) model, the functional renormalization group, and the holographic model with extended DeWolfe-Gubser-Rosen dilaton potential.

  1. 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.

  2. Scaling functions in the soft-wall AdS/QCD models

    hep-ph 2025-07 conditional novelty 5.0 of 10

    Soft-wall AdS/QCD models reproduce mean-field chiral scaling functions and follow a T_c scaling law whose slope, tuned by a modified potential, can approach Dyson-Schwinger results.

  3. 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.

  4. Schwinger Effect in a Twice Anisotropic Holographic Model

    hep-ph 2025-06 conditional novelty 4.0 of 10

    In a twice anisotropic holographic QCD model, magnetic anisotropy lowers the Schwinger pair-production barrier while spatial anisotropy raises it.
