ANALYSIS OF DCC DOMAIN-STRUCTURE

Wavelet-type methods are employed for the analysis of pion field confi gurations that have been obtained by dynamical simulations in idealize d scenarios relevant to the formation of disoriented chiral condensate s. It is illustrated how the measurement of the isospin domain structu re depends on the ability to zoom in on limited parts of the phase spa ce, due to the interplay between the pion correlation length and the e ffective source geometry. The need for advanced analysis methods is un derscored by the fact that the extracted neutral-fraction distribution would differ significantly from the ideal form, even under perfect ex perimental conditions, and, moreover, by the circumstance that thermal sources with suitably adjusted temperatures can lead to distributions that may be practically indistinguishable from those arising from DCC -type nonequilibrium evolutions.
