A partial-wave analysis of world data for the reaction π−p → K 0Λ from threshold to 2350 MeV/ c

Abstract

All available world data for the reaction π −p→K 0 Λ up to 2350 MeV/ c incident momentum have been analysed using both the Barrelet zero technique and a conventional energy-dependent fit. The results of the two methods are in good agreement. Resonances are required in the S 11, P 11, P 13 and D 13 partial waves. There is also an enhancement in the D 15 wave around 1900 MeV. No other resonances are required.
