We analyze the behavior of (net-)proton number cumulants in centralcollisions of heavy ions across a broad collision energy range by utilizinghydrodynamic simulations. The calculations incorporate essential non-criticalcontributions to proton fluctuations such as repulsive baryonic core and exactbaryon number conservation. The experimental data are consistent withnon-critical physics at collision energies $\sqrt{s_{\rm NN}} \geq 20$ GeV. Thedata from STAR and HADES Collaborations at lower collision energies indicate anexcess of (multi-)proton correlations over the non-critical reference. Thisobservation is discussed in the context of different mechanisms, including thepossibility of a critical point in the baryon-rich region of the QCD phasediagram.
