Abstract

Reaction K-p → π0π0 Λ was measured at eight incident K- momenta between 514 and 750 MeV/c using the Crystal Ball multiphoton spectrometer. The reaction dynamics are displayed in total cross sections, Dalitz plots, invariant-mass spectra, production angular distributions, and the Λ polarization. The π0π0 Λ production is dominated by the π0Σ0(1385) intermediate state; no trace of other light Σ* states is observed, and the role of the f0(600) meson appears to be insignificant. A striking similarity is seen between K -p → π0π0 Λ and π-p → π0π0n; this can be understood as a consequence of dynamical flavor symmetry.
