quarkonia

基本解釋

In the framework of quarkonia-quarkonia mixing, considering the effect of the flavor-dependent transitions between quarkonia, the new mass relation of a meson nonet is presented.
摘要在介子－介子混合的框架下，考慮到夸克偶素間的湮滅跟味道有關(guān)這種效應(yīng)，給出了一種新的介子九重態(tài)成員間的質(zhì)量關(guān)系。
It indicates that a correct mass relation of a meson nonet (especially for the non ideal-mixing meson nonet) should incorporate the effect of the flavor-dependent quarkonia annihilation.
這表明，一個正確反映介子九重態(tài)（特別是非理想混合的介子九重態(tài)）成員間質(zhì)量關(guān)系的公式，應(yīng)該包含夸克偶素間的湮滅跟味道有關(guān)這種修正。
