Multidimensional Analysis of the Three-Body Reaction π-p→π-π+n at 6 GeV/c

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 (ρ 0 n , f 0 n , g 0 n , 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.
