Transverse and longitudinal Bose-Einstein correlations in e+ e- annihilation
Jerusalem EPS HEP 97, 425-428 (1999)
We show 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 model. The difference is more apparent in genuine three-particle correlations and they are therefore a good probe for the longitudinal stretching of the string field.
