Note on mass enhancements and the Goldstone-pair mechanism

The irreducible components of the 1/2+ baryon mass matrix and the 0- meson mass-squared matrix are calculated and compared with the Li--Pagels relations. The Li--Pagels relations predict correctly orders of magnitude, but one sign is wrong and most of the relations are off by non-negligible factors. An exception is the relation [(m/sub p/ - m/sub n/) + 2(m/sub Σ+/-m/sub Σ-/) + (m/sub Ψ0/ - m/sub Ψ-/)]/(m/sub Ψ/ - m/sub N/) = -[3(m/sub K+/2 - m/sub K0/2) + 2√3(m/sub eta/2 - m(sub π0/2)sinβ cosβ](2m/sub K/2 + m/sub eta/2 - 3m/sub π/2), which is satisfied quite well. The angle β is the eta-π0 mixing angle
