A −2 production in π−p interactions at 3.9 GeV/ c

The reaction π −p → A − 2p at 3.9 GeV/ c incident momentum is studied using data corresponding to the ϱ ° π −, ηπ − and K δ sK − decay modes of the A − 2. Unnatural parity exchange is found to be important at this energy. The natural parity exchange component of the differential cross section exhibi...

Summary:The reaction π −p → A − 2p at 3.9 GeV/ c incident momentum is studied using data corresponding to the ϱ ° π −, ηπ − and K δ sK − decay modes of the A − 2. Unnatural parity exchange is found to be important at this energy. The natural parity exchange component of the differential cross section exhibits structure at t′ ≈ GeV 2.
