Abstract Results are presented on two-particle inclusive production inK + p interactions at 32 GeV/c. We study thex 1,2=x 1+x 2 dependence of invariant structure functions of (ππ)-pairs and compare them to single particle inclusive distributions in the fragmentation regions. Distributions of particles observed at Feynmanx 2 in association with various “trigger” particles or systems atx 1 in the same hemisphere are dicussed in terms of the reduced variable $$\tilde x_2 = x_2 /(1 - |x_1 |)$$ . We further present absolute production rates and production ratios of π+'s and π−'s associated with π±,K s 0 , Λ, $$\bar \Lambda $$ ,K *+ (890), (K s 0 π+), and (π+ π−)-triggers, and compare them with qualitative predictions of the quark recombination model. Forwardbackward correlations between (K s 0 π±), (K s 0 ,p), (Λ, π−), $$(\bar \Lambda \pi ^ \pm )$$ , and (p, π−) pairs are also discussed.
