流夸克间的唯象相互作用

Phenomenological interaction between current quarks

Michihiro Hirata, Naoto Tsutsui

摘要:

我们构造了一个描述QCD真空动力学手征对称性破缺的唯象模型,再现了介子谱。夸克凝聚,π衰变常数,介子光谱很好地再现的唯象相互作用,其中包括一个线性的限制势,库仑势,和't Hooft行列式的相互作用。在这个模型中,t Hooft行列式相互作用不仅对η,η'质量差起重要作用,而且通过DCSB对其它介子质量也起重要作用。

英文摘要:

We construct a phenomenological model which describes the dynamical chiral symmetry breaking (DCSB) of QCD vacuum and reproduces meson spectra. Quark condensates, the pion decay constant, and meson spectra are well reproduced by phenomenological interaction which consists of a linear confining potential, a Coulombic potential, and the 't Hooft determinant interaction. In this model, the 't Hooft determinant interaction plays a important role not to only η,η' mass difference, but other meson masses through DCSB.
