Wattenberg, A. Goodman, Maury Charles 2011-06-28T18:36:15Z 2011-06-28T18:36:15Z 10000-01-01 1979 A study of Zweig's rule using phi mesons in a high energy photon beam has been performed. Measurement of the ratio sigma (gamma A -> phi pi pi A) / sigma (gamma A -> omega pi pi A) = 0.10 ± 0.02 is taken as evidence that there is not as strong suppression as could be expected. Other ratios show strange particle production down from non-strange particle production by a factor of twelve. Decays involving phi mesons are studied, and the only candidate seen is a four sigma effect in the mode two phis with a mass 2.15 Gev. F meson, charm pseudo-scalar meson and exotic vector mesons which might decay into phis are not seen. The phi prime is not seen with an upper limit sigma (gamma A -> 'A) B (phi' -> K+K-pi+pi-) < 6 nb per nucleon.
