Reactions K-p-->Σ0π0 and K-p-->Λπ0 in the momentum range 240 to 450 MeV/c
Abstract
An analysis has been made of 57 600 events of the type K-p-->Λ + missing neutrals obtained in the Berkeley 25-in. hydrogen bubble chamber. The data were divided into intervals of 10 MeV/c in incident momentum and fits were made to the distribution in missing neutral mass, the production cosine, and the polarization of the Λ. These fits yielded Legendre coefficients describing the cross sections and polarizations for K-p-->Σ0π0 and K-p-->Λπ0 in the momentum range 240 to 450 MeV/c. The cross sections and polarization in the Σ0π0 final state show marked structure coming from the production and decay of Λ(1520). The cross sections and polarizations for the Λπ0 final state vary slowly. No new structure is observed.
