Résumé

In previous work, the E802 Collaboration at the BNL-AGS used negative binomial distribution (NBD) fits to charged particle multiplicity distributions from central collisions of [Formula Presented]O+Cu at [Formula Presented] GeV/[Formula Presented] to derive the two-particle short-range rapidity correlation length and strength. These turned out to be much shorter and weaker than the values for hadron collisions, which led to a simple and elegant explanation of intermittency. In the present work, a direct measurement of the two-particle correlation of identified pions in the E802/E859 magnetic spectrometer is performed in the interval [Formula Presented] for central [Formula Presented]Si+Au collisions, both in terms of [Formula Presented], where [Formula Presented], and also in terms of [Formula Presented] and [Formula Presented], where [Formula Presented] and [Formula Presented] are the four-momentum, pseudorapidity, and rapidity of the pions. It is demonstrated that the two-pion correlation in rapidity (and pseudorapidity) is entirely due to the Bose-Einstein interference. The directly measured correlation length in both [Formula Presented] and [Formula Presented] is [Formula Presented] for two [Formula Presented], with strength [Formula Presented]%, in agreement with the previous E802 indirect measurements derived from the NBD analysis of intermittency.
