meson-meson effect
解釋
介子相互作用-
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這種效應，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（特別是非理想混合的介子九重態）成員間質量關系的公式，應該包含夸克偶素間的湮滅跟味道有關這種修正。 -
The nucleon dbhf self - energy in the nuclear medium, therefore, can be calculated with the g matrix in the relativistic hartree - fock approximation. with the calculated nucleon self - energy in the dbhf, we extract nucleon effective interactions hi the framework of the relativistic mean field theory ( rmf ), which contains the effect of the nucleon - nucleon short - range correlation and information of the isospin structure. applying the effective interaction, which is composed of density dependent meson - nucleon coupling constants, we study the properties of finite nuclei and come to some useful conclusions
本文應用相對論dirac - brueckner - hartree - fock （ dbhf ）方法，利用新的g矩陣分解方式g = v + g ，用g矩陣在相對論hartree - fock近似下，即等效的dbhf方法，系統地討論了對稱、不對稱核物質及中子物質的性質，利用對稱及不對稱核物質中自能的dirac結構，我們提取出含有核子-核子短程關聯效應和同位旋結構信息的有效相互作用介子耦合常數，並對有限核的性質做了詳細的討論，得到不少有意義的結果。
