Sažetak
The SU(3) linear [sigma] model (L [sigma] M) is dynamically generated in loop-order using the non-strange-strange basis. Only self-consistent logarithmic divergent graphs are needed, with quadratic divergent graphs being replaced by SU(3) mass-shell equal splitting laws. The latter lead to an [eta] '- [eta] mixing angle of 41.84° which is consistent with phenomenology. Finally, this above SU(3) L [sigma] M in turn predicts strong decay rates which are all compatible with data.
