Abstract

Results from the analysis of Bose-Einstein correlations of negative pions produced in central collisions of S + S, S + Ag, S + Au and O + Au at 200 GeV/N in a wide rapidity range 0.5 < y < 4.0 are presented. At mid-rapidity a transverse source size significantly larger than the projectile radius is observed in central S + Ag and O + Au collisions. A strong dependence of transverse and longitudinal sizes with rapidity, rapidity density and total multiplicity is observed. For S + S and S + Au the midrapidity correlation functions can not be fitted with a Gaussian parametrization.

    Citation Excerpt :

    Bose-Einstein correlations are of interest to the LEP community as a source of systematic error in W-mass determinations (for example [1–4]), and also to the Heavy Ion community (see [5, 6]) as a valuable measurement tool for the size of the fireball created in heavy ion collisions (eg. [7]and refs therein).
