Abstract
We have analyzed the joint charged particle to photon density correlations in WA98 experiment at CERN-SPS in order to study the formation of the chirally disoriented vacuum in Pb + Pb collisions at 158 AGeV. The method of analysis is based on the event-by-event estimation of a set of robust observables which are the ratios of normalized bivariate factorial moments corrected for many efficiency factors. This is found to be a very powerful technique in identifying, within the limits of the detector resolution, the events with the localized charged particle to photon density fluctuations.
