摘要：

Segregation into ideally mixed nonets results when the OZI-violating interaction which would mix uū, dd̄, and ss̄ mesons into isospin and SU(3) eigenstates is much weaker than the ss̄dd̄ mass difference. We show that the dd̄uū mass difference can begin to induce a similar segregation into dd̄ and uū mesons which leads to large isospin violations. An experimental example of such large isospin breaking (≈30%) which we predict has probably already been seen in f → KK̄. © 1979.
