K(-)P ->Pi(0)Pi(0)Sigma(0) At P(K)(-)=514-750 Mev/C And Comparison With Other Pi(0)Pi(0) Production

Reaction K(-)p-->pi(0)pi(0)Sigma(0) was measured with the Crystal Ball multiphoton spectrometer at eight K- momenta from 514 to 750 MeV/c. Dynamics and the energy dependence of the reaction are shown by Dalitz plots, invariant mass spectra, production angular distributions, and total cross sections. The dipion invariant-mass spectra for K(-)p-->pi(0)pi(0)Sigma(0) show an enhancement in the low mass region; the opposite is the case for the K(-)p-->pi(0)pi(0)Lambda and pi(-)p-->pi(0)pi(0)n reactions. There is no direct evidence for a f(0)(600)-meson contribution to pi(0)pi(0) production. Everywhere sigma(t)(K(-)p-->pi(0)pi(0)Sigma(0))pi(0)pi(0)Lambda).
