Description
Results on inclusive PHI production in K-rho interactions at 110 GeV/c are prestented. The production cross section is found to be larger than in πrho and rhorho interactions at similar energies, suggesting OZI allowed santi s fusion to be the dominant mechanism in PHI production. The chi distributions of PHI and anti Ksup(*0) are found to be similar to each other over the entire chi range suggesting an overall strangeness suppression factor of 0.20+-0.04 in the sea to be the dominant source of the difference in the cross section for PHI and anti Ksup(*0). There is no evidence of a narrow PHIπ- state around 2.1 GeV/c2 as suggested by K+ experiments, but there is some excess of events in the region 1.94-1.98 GeV/c2 consistent with the F-meson mass as observed in e+e- experiments.
