Query: Fluctuation of Voids in Hadronization at Phase Transition   Starting from the recognition that hadrons are not produced smoothly at phase
transition, the fluctuation of spatial patterns is investigated by finding a
measure of the voids that exhibits scaling behavior. The Ising model is used to
simulate a cross-over in quark-hadron phase transition. A threshold in hadron
density is used to define a void. The dependence of the scaling exponents on
that threshold is found to provide useful information on some properties of the
hadronization process. The complication in heavy-ion collision introduces the
possibility of configuration mixing, which can also be studied in this
approach. Numerical criteria on the scaling exponents have been found that can
be used to discriminate phase-transition processes from other hadronization
processes having nothing to do with critical phenomena.
