nonet

1.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-介子混合框架下，考虑到夸克偶素湮灭跟味道有关这效应，给出新介子重态成员量关系。

2.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.

这表明，个正确反映介子重态（特别是非理想混合介子重态）成员量关系公式，应该包含夸克偶素湮灭跟味道有关这修正。
