A sample of 43000 two-prong events obtained at a momomentum of 11.7 GeV/c is used to determine the cross-sections of the fitted channels, and to study the reaction π+p→π+pπ0. We investigate in particular the quasi-two-body channels π0Δ++ and ρ+p.

Search for narrow resonances in the r region

Bowen, D. ; Earles, D. ; Faissler, W. ; et al.
Phys.Rev.Lett. 29 (1972) 890-893, 1972.
Inspire Record 75434 DOI 10.17182/hepdata.21418

We report on a measurement of the missing-mass, (mm)−, spectrum from the reaction π−+p→(mm)−+p at 8 GeV. The data contain 6500 events in the R peak (M2=2.72±0.02 GeV2, Γ=139±31 MeV). The R shape is consistent with either a single Breit-Wigner or several wide resonances, as suggested by bubble-chamber experiments, but inconsistent with the series of narrow resonances reported by the CERN missing-mass group.
