High-order cumulants and correlation functions near the critical point from molecular dynamics
Volodymyr A. Kuznietsov, Roman Poberezhniuk, Mark I. Gorenstein +2
We present a systematic investigation of particle number fluctuations in the crossover region near the critical endpoint of a first-order phase transition using molecular dynamics…

Proton cumulants from hydrodynamics in light of new STAR data
Volodymyr Vovchenko, Volker Koch
New measurements of proton number cumulants from the Beam Energy Scan Phase II (BES-II) program at RHIC by the STAR Collaboration provide unprecedented precision and insights into…

Acceptance dependence of factorial cumulants, long-range correlations, and the antiproton puzzle
Adam Bzdak, Volker Koch, Volodymyr Vovchenko
We analyze joint factorial cumulants of protons and antiprotons in relativistic heavy-ion collisions and point out that they obey the scaling $\hat{C}_{nm}^{p,\bar{p}} \propto \lan…
