Abstract

The process pn → ppπ^- is studied in pd collisions at 11.6 GeV/c. A broad low-mass enhancement of pπ^- is found in the diffractive reaction pn → p(pπ^-) with a cross section slightly smaller than that of a similar analysis at 7.0 GeV/c. The non-diffractive reaction pn → (pπ^-)p shows some evidence for resonance production and its cross-section dependence on energy is characteristic of meson exchange. Samples of mass, momentum transfer, and decay angular distributions are compared with the predictions of a double Regge model and a reggeized one-pion exchange model. Using in addition information from the reactions pp → ppπ⁰, pp → pnπ⁺ at 12.0 GeV/c, an isospin analysis of the single pion production reaction from nucleon-nucleon scattering, N₁N₂ → N₃(N₄π) is presented.
