Fluctuation probe of disoriented chiral condensates
Abstract
We show that an event-by-event fluctuation of the ratio of neutral pions or resulting photons to charged pions can be used as an effective probe for the formation of disoriented chiral condensates. The fact that the neutral pion fraction produced in case of disoriented chiral condensate formation has a characteristic extended non-Gaussian shape is shown to be the key factor which forms the basis of the present analysis.
