Particle Mixing andJP=2+Meson Decays

Abstract

Particle mixing for meson fields of arbitrary spin is considered in a field-theoretic context. Expressions for the field renormalization constants and mixing parameters are given in terms of the physical masses, assuming Okubo-type octet breaking. Broken-$\mathrm{SU}\left(3\right)\mathrm{}$ coupling constants are evaluated for the $2^{+}$ meson decays and the predicted partial widths compared with experiment. Satisfactory agreement is found.
