The BNL/CCNY group has observed and performed a partial wave analysis on 1203 (22 GeV) ..pi../sup -/p ..-->.. phi phi n events. The OZI suppression has been found to be almost completely broken down. The phi phi spectrum is found to be composed almost entirely of two new resonances, the g/sub T/(2160) and the g/sub T/(2320) with K/sup G/J/sup PC/ = 0/sup +/2/sup + +/. For g/sub T/ (2160), M = 2.16 +- 0.05 GeV, and GAMMA = 0.31 +- 0.07 GeV. For g/sub T/(2320), M = 2.32 +- 0.04, and GAMMA = 0.22 +- 0.07. Assuming (1) QCD is correct, and (2) the OZI rule is universal for weakly coupled glue in disconnected Zweig diagrams due to the creation or annihilation of new types of quarks; it is concluded that one or two primary glueballs with the above quantum numbers are responsible for the above observed states. 42 references.
