quarkonia

基本解释

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，考虑到夸克偶素间的湮灭跟味道有关这种效应，给出了一种新的介子九重态成员间的质量关系。
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.
这表明，一个正确反映介子九重态（特别是非理想混合的介子九重态）成员间质量关系的公式，应该包含夸克偶素间的湮灭跟味道有关这种修正。
