Description
We discuss the effects of the global baryon and electric charge conservation on the cumulants of net baryon and net proton fluctuations [1], which are considered to be sensitive probes of the QCD critical point. We show that the cumulants are substantially suppressed if the conservation laws are taken into account. We propose a new observable that is not influenced by the global baryon conservation but is highly sensitive to the critical end point or the crossover.
