TL;DR: In this paper, high-multiplicity proton-proton reactions at 10 GeV/c have been studied and the analysis of 1937 events has been obtained: reaction 1) pp→ppπ+π+δ+π−π−δ, σ=(0.64±0.16 in channel 1), 0.60± 0.12 in channel 2, and 0.48± 1.09 in channel 3.
Abstract: High-multiplicity proton-proton reactions at 10 GeV/c have been studied. In the analysis of 1937 events the following results were obtained: reaction 1) pp→ppπ+π+π−π−, σ=(0.46±0.04) mb, 2) pp→ppπ+π+π−π−π0 σ=(0.69±0.05) mb, 3) pp→ppπ+π+π−π−, σ=(0.54±0.04) mb, 4) pp→>1 neutral particle, σ=(0.76±0.05) mb. The fraction of Δ++ is 0.64±0.16 in channel 1), 0.60±0.12 in 2) and 0.48±0.09 in 3). There is evidence for production of Δ++(1920)→pπ+ in reaction 3) and Δ+(1920)→pπ0 in reaction 2). No significant evidence for other baryon resonances, meson resonances or double isobar production was found.
