SELF-CONSISTENT CALCULATION OF VECTOR- AND PSEUDOSCALAR-MESON MASS SPLITTINGS

It is shown that, within the framework of the model chosen, one can calculate in a completely self-consistent manner the medium-strong (MS) mass splittings within the vector- and pseudoscalar-meson octets. In particular, expressions for the mass splittings may be written down in terms of experimentally observable parameters, one of which, the ρ-π coupling constant gρπ2, is found to be equal to 0.526, in good agreement with the physically observed value 0.60. © 1968 The American Physical Society.
