Backward production in $\pi^{-}p \rightarrow p_{f}\pi^{+}\pi^{-}\pi^{-}$ reaction at 9 and 12 GeV/c
The authors have analyzed backward meson production in the reaction pi /sup -/p to p/sub f/ pi /sup +/ pi /sup -/ pi /sup -/ at 9 GeV/c and 12 GeV/c incident pi /sup -/ momenta, from an experiment performed at the CERN Omega Spectrometer using a fast proton (p/sub f/) trigger device. They find stron...

| description | The authors have analyzed backward meson production in the reaction pi /sup -/p to p/sub f/ pi /sup +/ pi /sup -/ pi /sup -/ at 9 GeV/c and 12 GeV/c incident pi /sup -/ momenta, from an experiment performed at the CERN Omega Spectrometer using a fast proton (p/sub f/) trigger device. They find strong production of quasi-two-body processes N* rho and N*f with a production mechanism consistent with u-channel nucleon exchange. At a lower level, N* pi processes with a 3-body baryon decay through Delta (1232) pi are observed. In the (3 pi )/sup -/ system, evidence is found for A/sub 1//sup -/ and clear A/sub 2//sup -/ backward production with similar cross sections ( approximately 0.5 mu b). (16 refs). |
