Tuan, S F

The contribution to K-meson--nucleon dispersion relations fronm the unphysical region due to absorption is examined in perturbation theory; it is found that the contribution need not be negligible for scalar K mesons or the case where Svlvania Electr has opposite relative parity from (K, ). The influence this has on a dispersion-theoretic analysis of K-meson scattering is noted. In the Appendix the mass relationships for a rigorous derivation of the dispersion relations are discussed.
