ANALYSIS OF CHARGED-PARTICLE-PHOTON CORRELATIONS IN HADRONIC MULTIPARTICLE PRODUCTION

In order to analyze data on joint charged-particle-photon distribution s from an experimental search (T-864, MiniMax) for disoriented chiral condensate (DCC) at the Fermilab Tevatron collider, we have identified robust observables, ratios of normalized bivariate factorial moments, with many desirable properties. These include insensitivity to many e fficiency corrections and the details of the modeling of the primary p ion production, and sensitivity to the production of DCC, as opposed t o the generic, binomial-distribution partition of pions into charged a nd neutral species. The relevant formalism is developed and tested in Monte Carlo simulations of the MiniMax experimental conditions.
