Analysis of NN $Yields$ ($Sigma$K)N and NN $Yields$ ($lambda$K)N channels at 6 GeV/c without isospin-exchange interference

An analysis of 6 GeV/c data for ten different charge channels belonging to the reactions NN yields ( SIGMA K)N and NN yields ( LAMBDA K)N is made in terms of the one-pion-exchange model and the Deck model. Different charge channels are combined in such a way that interferences between isoscalar and isovector exchanges are eliminated. The results of earlier isospin analyses are used to fix the relative proportions of these exchanges for any particular charge channel combination. The model analysis gives a satisfactory semi-quantitative explanation of the data, and in particular of the longitudinal phase space distributions upon which the earlier isospin analyses were based.
