abstract
Several approaches to QCD with two massless quarks at finite temperature T and baryon chemical potential mu suggest the existence of a tricritical point on the boundary of the phase with spontaneously broken chiral symmetry. In QCD with massive quarks there is then a critical point at the end of a first order transition line. We discuss possible experimental signatures of this point, which provide information about its location and properties. We propose a combination of event-by-event observables, including suppressed fluctuations in T and mu and, simultaneously, enhanced fluctuations in the multiplicity of soft pions.

The mid-rapidity curvature of Δv₁^even(p − p̄) is proposed as a robust discriminator of initial-state baryon rapidity profiles motivated by double-junction stopping.
Landau singularity analysis of two-point functions in Schwinger-Keldysh EFTs identifies nonlinear relaxation modes that produce power-law late-time decay when gapless modes are present.
Deterministic confluent equations are derived for three-point correlations of non-Gaussian fluctuations in relativistic stochastic hydrodynamics, including fluctuating velocity, using a covariant formalism in the average local Landau frame.
A conditional probability framework derives Maxwell-Boltzmann, Bose-Einstein and Fermi-Dirac statistics plus conservation-induced covariances from saddle-point marginals, then uses orthogonal projections to isolate conservation effects in PYTHIA-simulated p+Pb events.
Derives diffusion matrix elements for baryon, charge, and strangeness transport in relativistic hydrodynamics from entropy production within the relaxation-time approximation.
A simplified model reproduces the observed non-monotonic pT correlation minimum via meson-baryon mixing, showing it is not a reliable signal for the QCD critical point.
The symmetry-improved CJT formalism yields stable global thermodynamic quantities across different pressure prescriptions in the three-flavor linear sigma model, with quantitative differences near the chiral transition.
A quark-meson model with lattice-fitted temperature-dependent quark masses and anomalous magnetic moments reproduces the magnetic susceptibility of hot hadronic matter up to the QCD crossover, showing quarks are active below 120 MeV.
In a constructed QCD equation of state incorporating surface energy, critical exponents require temperature within 1% of the critical value, casting doubt on their measurability in heavy ion experiments.
A physics-informed neural network produces a thermodynamically consistent 4D equation of state for QCD matter that reproduces lattice QCD and hadron resonance gas results while extrapolating to high baryon density for use in hybrid hydrokinetic models.
Soft modes linked to the QCD critical point and two-flavor color superconductivity in the NJL model produce a pseudogap above Tc and enhance electric conductivity and dilepton rates relevant to heavy-ion collisions.
The MUSES Calliope engine computes multi-dimensional QCD equations of state, merges them consistently, and feeds them into viscous hydrodynamic simulations of heavy-ion collisions with movable critical points and critical scaling in transport coefficients.
