英文摘要 | We investigate the decay of f(1)(1285) -> pi K (K) over bar with the assumption that the f(1)(1285) is dynamically generated from the K*(K) over bar + cc interaction. In addition to the tree level diagrams that proceed via f(1)(1285) -> K*(K) over bar + cc -> pi K (K) over bar, we take into account also the final state interactions of K (K) over bar -> K (K) over bar and pi K -> pi K. The partial decay width and mass distributions of f(1)(1285) -> pi K (K) over bar are evaluated. We get a value for the partial decay width which, within errors, is in fair agreement with the experimental result. The contribution from the tree level diagrams is dominant, but the final state interactions have effects in the mass distributions. The predicted mass distributions are significantly different from phase space and tied to the K*(K) over bar + cc nature of the f(1)(1285) state. |
