Abstract:
We present results on an amplitude analysis of the K+K- system produced in the reaction π-p→K+K-n from threshold up to 2.2 GeV. The branching ratios of f0 and f' to KK have been determined. In the low mass region of the KK system the observation of an S-wave enhancement at 1.3 GeV and the interference of the f0-A2-f' mesons are studied. We observe a 3- structure in the mass region of 1.7 GeV which is consistent with g0 production. With this interpretation the branching ratio g→KK has been determined. Evidence for a new structure in the Jp = 2+ wave around 1.8 GeV with a width of ∼200 MeV is presented.
