New data on the reaction K −n → ( Σπ) − and a partial wave analysis of [formula omitted] in the energy range 1520–1745 MeV

Abstract

Differential cross sections for K − n → Σ o π o have been measured at K − momenta between 680 and 840 MeV/ c in a bubble chamber experiment. For K −n → Σ o π − the Σ o polarization was also determined. The measurements were combined with the available data on K −p → Σπ in an energy-dependent partial wave analysis in the center of mass energy range from 1520 to 1745 MeV. An acceptable fit was obtained with the well established resonances.
