For the hadronic collisions, the effect depends for soft hadronic data. The results differ strongly from the overall behavior in e+e' data, but the angular dependence of the particle-particle correlation (PPC) and its asymmetry ( PPCA) A sample of non-diffractive vrfp and Kip collisions at \/5:22 GeV is used to investigate Abstract. 289 M.
