ANGULAR-DEPENDENCE OF PARTICLE CORRELATIONS IN PI(+) K(+)P INTERACTIONS AT 250 GEV/C/

A sample of non-diffractive pi(+)p and K(+)p collisions at root s = 22 GeV is used to investigate the angular dependence of the particle-par ticle correlation (PPC) and its asymmetry (PPCA) for soft hadronic dat a. The results differ strongly from the overall behavior in e(+)e(-) d ata, but agree with that expected for e(+)e(-) 2-jet data. For the had ronic collisions, the effect depends strongly on the charge configurat ion of the pairs and on the rapidity range covered. The FRITIOF Monte Carlo model gives qualitative agreement with the trend of the overall data when Bose-Einstein correlations are included, but differs conside rably in the central rapidity region.
