Abstract
The authors investigate theoretical interpretations of the 1.4 GeV J{sup PC} exotic resonance reported by the E852 collaboration. It is argued that interpretation in terms of a hybrid meson is untenable. A K-matrix analysis shows that the 1.4 GeV enhancement in the E852 {eta}{pi} data can be understood as an interference of a non-resonant Deck-type background and a resonance at 1.6 GeV. A final state rescattering calculation shows that the 1.6 GeV hybrid has a {eta}{pi} width which is bounded above by 57 {+-} 14 MeV.
