A partial wave analysis of the (Kππ) system in the reaction π− p→(K +π−π0)Λ at 3.95 GeV/c

Abstract

Results from a partial wave analysis of theKππ system produced in the hypercharge exchange reaction π− p→(K +π−π0)Λ at 3.95 GeV/c are presented. SignificantQ 1 production is observed but no evidence is found forQ 2 production thus confirming the results obtained in a previous decay Dalitz plot analysis of the same reaction. The relative phase behaviour of the 1+(Kϱ) partial waves obtained with the present analysis provides additional confirmation of the resonance interpretation of theQ 1 enhancement. Information is also obtained about its production properties and the role played by the Λ polarization in the hypercharge exchange reaction. This is compared with the results obtained in the reactionK − p→(π+π−π0)Λ at 4 GeV/c.
