f,f', and A/sub 2//sup 0/ interference in. pi. N. -->. K/sup -/K/sup +/N at 6 GeV/c

Journal Article · · Phys. Rev. Lett.; (United States)
The Argonne effective mass spectrometer has been used for a high-statistics study of ..pi../sup -/+p..-->..K/sup -/+K/sup +/+n (110,000 events) and ..pi../sup +/+n..-->..K/sup -/+K/sup +/+p (50,000 events) at 6 GeV/c. Comparison of the two reactions allows isolation of the interference between K/sup -/K/sup +/ states of differing isospin. We observe f-A/sub 2//sup 0/, f'-A/sub 2//sup 0/, and f-f' interferences in the Y/sub 4//sup 0/ moment and find f' production to have a substantial contribution from some mechanism besides pion exchange. New values for the f' mass, width, and branching ratio into ..pi pi.. are presented. (AIP)
