Abstract
Under the hypothesis that the K-meson interactions do not mask the symmetries of the pion-baryon interactions appreciably, the branching ratios of the K-+p reactions are studied to test the validity of global symmetry. The T-1-matrix formalism of Matthews and Salam is adopted to calculate the branching ratios. The new Dalitz-Tuan solutions for K̅ N scattering lengths, which incorporate the (K+, K0) mass difference and the new branching ratios of the various K-+p reactions, presented at Kiev, are adopted in the analysis. The errors in the experimental branching ratios are so chosen as to satisfy the Amati-Vitale inequality. It is found that the a- and b+ (also a+, though poorly) Dalitz-Tuan solutions can explain the branching ratios for K- captured at rest. The extension of the analysis to 30-Mev incident K- mesons under the zero-range approximation leads to very poor agreement with experiments.
