Production mechanism in the four-body reaction π+n → pπ+π−π0 at 5.1 and 9 GeV/c

1975 
Abstract The π + n → p π + π − π 0 reaction is studied in the longitudinal phase space (LPS). The cross sections, mass spectra and four-momentum transfer distributions are discussed in each LPS sector. The dominant processes seem to be the ΔQ = 0 and G parity positive exchange, and ΔQ = 0, 1 and G parity negative exchange. A low baryon diffraction dissociation is also present.
