Abstract
We perform an amplitude analysis of 10 GeV/ c π −p → K −K S 0p data as a function of K −K 0 mass from threshold up to 2 GeV. We find that the A 2 and g resonances are produced dominantly by natural and unnatural parity exchange, respectively, and we determine their resonance parameters. We present further evidence for the I = 1, 4 + state A 2 ∗(1900), in particular by isolating interference effects. The structure of S-wave K −K 0 production suggests an I = 1, 0 + state just below 1300 MeV of width about 250 MeV.
