Enhancement of Ω and Ω̄ baryon production in Pb+Pb collisions at a center-of-mass energy of 17A GeV can be explained by the formation of many small disoriented chiral condensate regions. This explanation implies that neutral and charged kaons as well as pions must exhibit novel isospin fluctuations. We compute the distribution of the fraction of neutral pions and kaons from such regions. We then propose robust statistical observables that can be used to extract the novel fluctuations from background contributions in π0π± and KS0K± measurements at the Brookhaven Relativistic Heavy Ion Collider and the CERN Large Hadron Collider.
