Abstract

Results of the investigation of some correlation effects in π-p interactions at 40 GeV/c incident momentum are given. On the basis of 2 000 events the dependence of the transverse momenta of π+ and π- mesons on the longitudinal momenta was obtained, as well as two- particle distributions for various pion pairs, and correlation functions C(y1, y2) and R(y1, y2). For π+π- pairs R(0,0) = 0.65 ± 0.07 and the correlation length is L = 1.8 ± 0.2 for -1 ≤ y1, y2 ≤ 1. For π+π+ and π-π- pairs R(0,0) = 0.26 ± 0.10. Comparison of these results with proton-proton data at 200 GeV and at ISR energies suggests that limiting behaviour in two- particle distributions R(y1,y2) for π-p interactions is already reached at 40 GeV.
