Three-body dispersion-relation N/D equations for the coupled decay channels ppbar (JPC=0-+) --> pi0 pi0 pi0, eta pi0 pi0, eta eta pi0, K Kbar pi0
Abstract
During several years the data on different channels ppbar (JPC=0-+) --> 3 mesons presented by Crystal Barrel Collaboration were successfully analyzed by extracting the leading amplitude singularities - pole singularities - with the aim to obtain information about two-meson resonances. But these analyses do not take into account three-body final state interactions (FSI) in an explicitly correct way. This paper is devoted to the consideration of this problem.
