PRODUCTION OF KK-BAR-PAIRS IN PHOTON PHOTON COLLISIONS AND THE EXCITATION OF THE TENSOR MESON F'(1515)
We have observed exclusive production of K+K- and KSOKSO pairs and the excitation of the f′(1515) tensor meson in photon-photon collisions. Assuming the f′ to be production in a helicity 2 state, we determine Λ(f′ → γγ) B(f′ → KK) = 0.11 ± 0.02 ± 0.04 keV. The non-strange quark of the f′ is found to...
