Abstract

The observed Bose-Einstein enhancement e +e − annihilation is well accounted for by a string model, ignoring resonance production and final state interactions. The data are scarcely compatible with the model when resonance production and like pion final state interactions are taken into account, for both these effects suppress the predicted enhancement. I show that multiparticle final state interactions should not be neglected and that isospin zero final state interactions enhance substantially the correlation, compensating for the repulsive isospin 2 effects.
