Description
The decay of the axial f1 (1425) meson through the chain f1 → K*K-bar (K-bar* K) → K K-bar π is considered in the model, which incorporates the pole diagrams and the triangle diagram. The analysis is motivated by recent observation of the state with the K* K-bar (K-bar* K) decay mode in the reaction pp-bar → (K K-barπ) ππ at rest. A nonrelativistic approach is used. Final-state K K-bar rescattering through α0(980) production is taken into account in the triangle diagram
