Coupling Types and Strengths of theY-N-KInteractions
Reiji Sugano, Akira Komatsuzawa · Progress of Theoretical Physics · 1960
Analyses are made on K-N scattering with use of the dispersion relations for the charge exchange scattering K+n→K0p and for the ordinary elastic scattering K+p→K+p. It is shown that (ΛNK) and (ΣNK) interactions are both pseudoscalar types or pseudoscalar and scalar types, respectively. As for the interaction strengths, it is preferable that gΛ2≈5 and gΣ2=0 with the existing experimental data.
