Abstract
The JP=0− partial waves of the Kππ system in the reactions K±p→K±π+π−p at 13 GeV are presented. Structure in intensities and relative phase variations suggest the existence of a pseudoscalar resonance, the K′, with a mass of ∼1400 MeV and a width of ∼250 MeV decaying predominantly into εK.
