HYPERON-NUCLEON INTERACTIONS IN A CHIRAL SU(3) QUARK MODEL

摘要

Quark-chiral field interaction is studied in terms of the linear realization of the Lagrangian which is invariant under the SU(3)(L) x SU(3)(R) infinitesimal transformation and then is applied to the hyperon-nucleon scattering calculation in the framework of RGM, It is shown that the SU(3) chiral scalar fields affect the spin dependence of the Lambda-N interaction and can improve the theoretical Sigma(-)p scattering cross section.
