Proton correlations

Presentation on proton cumulants at the Workshop on High Baryon Density Physics in High-Energy Nuclear Collisions at LBNL.

Presentation on disentangling equation of state and canonical ensemble effects on proton fluctuations via a density correlations formalism at the APS Global Physics Summit 2026.

We analyze the behavior of ordinary and factorial cumulants of proton number in heavy-ion collisions in the context of new RHIC-BES-II data, their implications for the QCD critical point search, as well as the behavior of scaled factorial cumulants of protons and antiprotons, pointing out challenges in describing antiprotons and possible incomplete equilibration between stopped and produced matter in heavy-ion collisions.
