Sangyong Jeon LBNL When the number of produced particles are small and under a conservation law, the event-by-event fluctuation of its multiplicity is very different from what one would expect from the grand-canonical ensemble. The behavior of the fluctuation and the related first factorial moment provide good probes for the degree of chemical equilibration and the initial population of the rare particles.
