Angular dependence of particle correlations in π+K+p eractions at 250 GeV/c

Abstract A sample of non-diffractive π + p and K + p collisions at s =22 GeV is used to investigate the angular dependence of the particle-particle correlation (PPC) and its asymmetry (PPCA) for soft hadronic data. The results differ strongly from the overall behavior in e + e − data, but agree with that expected for e + e − 2-jet data. For the hadronic collisions, the effect depends strongly on the charge configuration 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 considerably in the central rapidity region.
