APPLICATION OF THE SERBER POTENTIAL TO LOW ENERGY HYPERON-NUCLEON SCATTERING
Theoretical expressions for the hyperon-nucleon scattering cross sections at low energy are derived which give these cross sections as simple linear combinations of the nucleon-nucleon cross sections. The assumptions necessary for this derivation are: (a) there exists a universal ooupling between pions and baryons, and (b) the nucleon-nucleon interaction can be described by a Serber potential. In addition, the approximations must be made of neglecting effects of K mesons and baryon mass differences. The restriction to low energy- is necessary because thc assumption is needed that the scattering be appreciable only when the hyperon and nucleon are in a state of zero orbital anguar momentum.
