abstract
We investigate the effect of the global charge conservation on the cumulants of conserved charges observed in relativistic heavy ion collisions in a finite rapidity window, $\Delta\eta$, with a special emphasis on the time evolution of fluctuations in the hadronic medium. It is argued that the experimental result of the net-electric charge fluctuation observed by ALICE does not receive effects from the global charge conservation, because of the finite diffusion distance of charged particles in the hadronic stage. We emphasize that the magnitude of the effect of the global charge conservation can be estimated experimentally by combining the information on the $\Delta\eta$ dependences of various cumulants of conserved charges, similarly to other dynamical properties of the hot medium.

Local baryon conservation in a canonical ensemble drives net-proton κ6/κ2 to small or negative values in restricted acceptance, establishing a baseline that must be subtracted before interpreting signals of chiral criticality.
