The reaction pp to 2 pi /sup -/2 pi /sup +/ at intermediate energies
Systematic features of the channel pp to 2 pi /sup -/2 pi /sup +/ are examined in the antiproton momentum range 2.5 to 4.6 GeV/c. It is found that as the antiproton momentum increases, exchange effects become increasingly important and a 'leading pion' emerges. This pion leaves a 'clu...

| Sumario: | Systematic features of the channel pp to 2 pi /sup -/2 pi /sup +/ are examined in the antiproton momentum range 2.5 to 4.6 GeV/c. It is found that as the antiproton momentum increases, exchange effects become increasingly important and a 'leading pion' emerges. This pion leaves a 'cluster' of three pions which preferentially decays to a pion plus a two-pion resonance ( rho , f, g mesons). The cluster is found to possess relatively weak internal directional properties. Both the leading pion and the pions in the cluster possess high transverse momenta. (0 refs). |
