Abstract

In an investigation of the final states K −π −π +π Op and K −π −π +π +n produced in K −p interactions at 4.6 and 5.0 GeV/ c we have observed narrow enhancements near 960 MeV in both the π +π −π O and π +π +π − distributions. These structures are strongly associated with the Δ(1236). Also, there is evidence for a possible ϱπ decay for these effects.
