It is found that the correlations from the neutral-resonance decays are important, yielding about a half of the total contribution, which in general consist of resonance and non-resonance parts. The model yields the pionic balance function a few per cent wider that what follows from the recent data for the Au+Au collisions at 130GeV.Error in the calculations correctedNuclear TheoryHigh Energy Physics - PhenomenologyNuclear Experimenttext
