Abstract

Reaction K ^-p→π⁰π⁰∑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→π⁰π⁰∑⁰ show an enhancement in the low mass region; the opposite is the case for the K ^-p→π⁰π⁰Λ and π^-p→π⁰π⁰π reactions. There is no direct evidence for a f₀(600)-meson contribution to π⁰π⁰ production. Everywhere σ_t(K ^-p→π⁰π⁰∑⁰) ≪σ(K^-p→π⁰π⁰Λ).
