A fundamental question in QCD is the existence of a phase transition at large doping of quarks over antiquarks. We present the first prediction of a QCD critical point (CP) from a Bayesian analysis constrained by first principle results at zero doping. We employ the gauge/gravity duality to map QCD onto a theory of dual black holes. Predictions for the CP location in different realizations of the model overlap at one sigma. Even if many prior samples do not include a CP, one is found in nearly 100\% of posterior samples, indicating a strong preference for a CP.

    First mapping of the QCD critical surface in full (T, μ_B, μ_Q, μ_S) space via constant-entropy expansion gives a critical point at (114, 602) MeV in the pure baryon direction, with μ_B,c shifting 40-100 MeV in strang...

    hep-ph 2026-07 conditional novelty 6.0

    Including Fierz-complete four-quark interactions in fRG-QCD shifts the predicted critical endpoint to (T, μ_B) = (102, 647) MeV and slightly increases the phase boundary curvature to κ₂ = 0.0151, while confirming σ an...

  3. Hadronic and partonic composition of QCD matter across the crossover

    nucl-th 2026-07 conditional novelty 4.0

    A three-parameter hadron–quark crossover equation of state fitted to lattice QCD data yields a switching temperature T₀ ≃ 216 MeV, implying hadronic degrees of freedom persist well above the chiral pseudocritical temperature.
