Description
Event-by-event fluctuations, such as those of charged-particle multiplicities, mean transverse momentum and particle ratios, have been identified as sensitive observables for the study of QCD phase structure, giving access to the thermodynamics of the medium created in heavy-ion collisions and to the possible existence of a critical point. I will review the current experimental picture from fluctuation measurements across collision energies, with a focus on recent high-precision results from the RHIC Beam Energy Scan, and outline the prospects for upcoming measurements at current and future facilities.
