The longitudinal and transverse momentum distributions of protons and π±-mesons, produced and pp interactions at close energy (22-24 GeV), are compared. The existence of a difference between these (P<1.2 GeV/c in laboratory system) and for mesons accompaying them, is shown. The observed difference increases with increasing the multiplicity of charged particles. For π+ mesons it increases with decreasing the momentum of accompaying protons. These effects do not practically exist for π- mesons

The inclusive process π++P→K¯ *0(890)+X is studied at 16 GeV/c using a 2-m streamer chamber containing a central liquid hydrogen target. From photographs triggered by detection of a forward K− meson, the signal K¯ K−*0π+ is extracted. The inclusive rate for K¯ * production into the forward hemisphere σ(xF>0.3) is 115±27 μb; the pT2 distribution is found to have a slope constant of 3.3±0.6 (GeV/c)2. The Feynman-x distribution for K¯ *0 is consistent with a Kuti-Weisskopf model in which the valence and sea quarks of the incident pion interact with only the sea quarks of the target proton.
