The 1.4 GeV JPC = 1-+ state as an interference of a non-resonant background and a resonance at 1.6 GeV
Alexander Donnachie, Philip R. Page
Abstract
We investigate theoretical interpretations of the 1.4 GeV JPC exotic resonance reported by the E852 collaboration. 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.
