Abstract
The analysis of 18 900 V O events is presented, with reference to the production of K K and K Kπ resonances in the three-, four-, five- and six-body final states. It is established that there is a threshold structure in the ( K K) I=1 state which comes entirely from the decay of K Kπ resonances, the D O and E O. The S ∗ and E O are definitely observed. The isospin of the D O is confirmed to be 0, J D O ⩾1 and, under the assumption L D ω =0, J D PC =1 ++. The F 1 is observed in the final state F 1 η O and the analysis of this channel leads to the conclusion that J F 1 PC =1 +− or 2 − In the five-body final state there is some appearance of two-peaks in the D O mas region, but with the present statistics there is no clear evidence for this effect. The cross sections for single and associated resonance production are given.
