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 p0-¿ and ¿-¿ are found to agree with the experimental data. A new and specific method of analysis is proposed and successfully tested.
