“…These analyses, though, require quantitative comparisons between theory and experiment, which for event-by-event fluctuations involve many caveats (see e.g. [16] for an overview). Addressing these caveats requires extensive dynamical modeling of heavy-ion collisions.…”

We present an overview of recent theoretical results on fluctuations of conserved charges in heavy-ion collisions obtained in relativistic hydrodynamics and molecular dynamics frameworks. In particular, we discuss the constraints on the location of the QCD critical point based on comparisons of experimental data on proton number cumulants with precision calculations of noncritical contributions. We also cover recent developments on critical fluctuations in molecular dynamics simulations.

“…Quantitative comparisons between experimental measurements and theoretical expectations of event-by-event fluctuations are challenging due to the many caveats involved [11], and thus require extensive dynamical modeling of heavy-ion collisions. In the context of the search for the QCD critical point, one can consider different strategies.…”

We analyze the behavior of (net-)proton number cumulants in central collisions of heavy ions across a broad collision energy range by utilizing hydrodynamic simulations. The calculations incorporate essential non-critical contributions to proton fluctuations such as repulsive baryonic core and exact baryon number conservation. The experimental data are consistent with non-critical physics at collision energies √ s NN ≥ 20 GeV. The data from STAR and HADES Collaborations at lower collision energies indicate an excess of (multi-)proton correlations over the non-critical reference. This observation is discussed in the context of different mechanisms, including the possibility of a critical point in the baryon-rich region of the QCD phase diagram.

I present an overview of recent theoretical results on fluctuations of conserved charges in heavy-ion collisions obtained in relativistic hydrodynamics and molecular dynamics frameworks. In particular, I discuss the constraints on the location of the QCD critical point based on comparisons of experimental data on proton number cumulants with precision calculations of non-critical contributions. Recent developments on critical fluctuations in molecular dynamics simulations are covered as well.
