Implications of Approximate SU_{3} Symmetry and Mass Formulas for the Mesons
Abstract
The connection between the limit of perfect SU_{3} symmetry and the zero mass approximation for the pseudoscalar meson octet is discussed. The wellknown quadratic mass formula for the pseudoscalar meson octet and the linear mass formula for the baryons are derived. A simple model of strong interaction is presented which leads to two mass formulas for the nine spin1 mesons: 2M_{φ}+M_{ρ}+M_{ω}=4M_{K*} and M_{ρ}≅M_{ω}. The general invariance property of this model which contains, among others, a baryon octet, a pseudoscalar octet, and a vector nonet is examined.
