ϱ-ω interference in p-annihilation at rest into π+π−η
Year: 1997
Type: article
Abstract: The π+π− invariant mass distribution produced in pp annihilation at rest and recoiling against η mesons exhibits large interference between the amplitudes for ϱη and ωη production. The interference can be quantitatively described within the framework of ϱ-ω interference. We find full coherence between the ϱω-ωη production amplitudes and a vanishing relative production phase. The implications of this result for pp annihilation dynamics are discussed.
