Three-particle Bose-Einstein correlations - a sensitive probe for Lund string fragmentation

• I discuss how a difference in the correlation length longitudinally and transversely with respect to the jet axis in e+e- annihilation, arises naturally in a model for Bose-Einstein correlations based on the Lund string picture. This difference is, due to the longitudinal stretching of the field, more apparent in genuine three-particle correlations. They can therefore be used as a sensitive probe of Lund string fragmentation.
