Abstract
The decay pp (at rest) → KLoK±π ∓πo, studied on a sample of more than 14000 events, is found to proceed dominantly via two-body channels containing resonances with open strangeness. Contributions from K1(1270)K and K1(1400)K, branching into the successive K1-decay modes, and from K∗K∗, K∗(Kπ)s and (Kπ)s(Kπ)s are extracted by means of a partial-wave analysis which accounts well for the data and also allows a search for weak contributions from other (Kππ) and from (KKπ) resonances. Striking asymmetries between the charged and the neutral kaonic resonances give evidence for interfering isospin 0 and 1 annihilation amplitudes.
