摘要：

The strangeness production process ppBAR --> LAMBDALAMBDABAR is studied in the K*-K** Regge pole approach with exchange degeneracy and absorption. An improved parametrization of the Regge amplitude is adopted. The absorption is approximated by distortion factors for initial and final states. An overall good description of cross section and spin observables is achieved down to very low energies.
