Resum

The quenched approximation of lattice QCD for Wilson fermions is used to calculate isospin breaking effects in the pseudoscalar- and vector-meson nonets. Mass differences inside the K and K* isodoublets and mixing phenomena for π0-η and ρ{variant}-ω are found to agree with the experimental data. A new and specific method of analysis is proposed and successfully tested. © 1989.
