Multidimensional void fluctuation: A search for quark–hadron phase transition

The event-by-event fluctuation of hadronic patterns is investigated by finding a measure of the nonhadronic regions, the voids, for the experimental data of 32S–AgBr interactions at 200 A GeV. Two lowest moments of the event-to-event fluctuation of voids, 〈Gq〉 and Sq have been defined by R.C. Hwa and Q.H. Zhang to quantify the dependence of the voids on the bin sizes. Characteristic of the quark–hadron phase transition, if any can be efficiently extracted from the scaling behavior of the voids. The experimental data of π−-AgBr interactions at 350 GeV/c are also probed with the same tool to have a complete view. The results have been compared with the results of the VENUS generated data for the above interactions.
