Pinsky, S S

An analysis of eight two-body Okubo-Zweig-Iizuka-rule-violating decays of psi to a vector and a pseudoscalar is carried out. The analysis uses the vector-dominance model and a standard parametrization of the Okubo-Zweig-Iizuka (OZI) process. It is pointed out that for two of the rates a second-order OZI process makes a substantial contribution. Seven of the eight rates are consistent with each other and the model; only psi..--> omega..eta is inconsistent. The average value of G/sub omegarhopi/ extracted from the data is 8.85 GeV/sup -1/, consistent with the chiral result G/sub omegarhopi/ = m/sub rho/ /sup 2//..pi../sup 2/F/sub ..pi../ 3 = 9.3 GeV/sup -1/.
