Popis: The reaction π − A → K + K − π − A was studied at the momentum of 37 GeV/c on the beryllium target at the wide aperture VES spectrometer. The partial-wave analysis of the K + K − π − system produced at low | t ′| 2 was performed. It is shown that in the wave with J P = 0 − there exists an object withmass 1.79±0.014 GeV/c 2 and width 0.21±0.07 GeV/c 2 decaying into κK − and | 0 (975) π − .
