We report on a study of 15-GeV/c π+p interactions of all topologies using the SLAC 82-in. hydrogen bubble chamber. A description is given of the automatic pattern-recognition techniques used to measure the events. Cross sections are given for meson-resonance production in all topologies. Evidence is presented for a new resonance decaying to five pions. A measurement is made of the branching ratios of the g meson. A study is made of low-mass enhancements in the diffractively produced ρπ, fπ, and gπ channels, and a search is made for nondiffractive production of the A1 meson.

Studies have been made of the reactions π + p→p π + π + π − and π − p→p π + π − π − , both at an incident pion momentum of 18.5 GeV/ c . The two-body (primarily Δ ++ and ϱ o and three-body (low-mass A enhancement, A 3 , N ∗ (1400), and N ∗ (1700)) subsystems are discussed. Cross sections for all significant channels of the reactions are given.
