    Abstract

    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 16O+Cu at 14.6A GeV/c 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 1.5≤y≤2.0 for central 28Si+ Au collisions, both in terms of Qinv= √|q|2-q20 where q=p2-p1=(q,q0), and also in terms of |η21| and |y2-y1|, where p, η, and y 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 η and y is ξ=0.19±0.03 for two π-, with strength R(0,0)∼l%, in agreement with the previous E802 indirect measurements derived from the NBD analysis of intermittency.
