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－介子混郃的框架下，考慮到誇尅偶素間的湮滅跟味道有關這種傚應，給出了一種新的介子九重態成員間的質量關系。
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（特別是非理想混郃的介子九重態）成員間質量關系的公式，應該包含誇尅偶素間的湮滅跟味道有關這種脩正。
