Abstract

A study of the reaction π⁻p→π⁻π⁺n at 6 GeV/c incident momentum has been made using the prism plot analysis (PPA) to reject multineutral contaminations and to separate various reaction channels (ρ⁰n, f⁰n, g⁰n, π⁻Δ⁺, π⁻(π⁺n)_DD). We can improve separability of PPA by incorporating decay angular distributions of resonances. Cross sections, invariant mass distributions, and production and decay angular distributions are presented.
