论文摘要
我们研究五夸克的光$ q^4 \ bar q $和隐藏的重物$ q^3 q \ bar q $（q = u，d，d，s quark in Su（3）风味对称性； q = c，b Quark）系统，具有一般群体理论方法中的一般群体理论方法，在构成Quark模型中，以及$ quark spectrum and $ Q $ quard $ quard $ quark an以及$ q^4 \ bar q $ pentaquark组件。该模型拟合到基态重子和轻度重子共振，据信是正常的三夸克状态。 The work reveals that the $N(1535)1/2^{-}$ and $N(1520)3/2^-$ may consist of a large $q^4\bar q$ component while the $N(1895)1/2^{-}$ and $N(1875)3/2^-$ are respectively their partners, and the $N^+(1685)$ might be a $q^4\bar q$ state.顺便说一句，紧凑型Pentaquark图片中的$ Q^3 Q \ bar Q $系统的一组新的颜色塑料空间波函数是系统地构造的，用于研究隐藏的魅力pentaquark States。
We study pentaquark states of both light $q^4\bar q$ and hidden heavy $q^3 Q\bar Q$ (q = u,d,s quark in SU(3) flavor symmetry; Q = c, b quark) systems with a general group theory approach in the constituent quark model, and the spectrum of light baryon resonances in the ansatz that the $l=1$ baryon states may consist of the $q^3$ as well as $q^4\bar q$ pentaquark component. The model is fitted to ground state baryons and light baryon resonances which are believed to be normal three-quark states. The work reveals that the $N(1535)1/2^{-}$ and $N(1520)3/2^-$ may consist of a large $q^4\bar q$ component while the $N(1895)1/2^{-}$ and $N(1875)3/2^-$ are respectively their partners, and the $N^+(1685)$ might be a $q^4\bar q$ state. By the way, a new set of color-spin-flavor-spatial wave function for $q^3 Q\bar Q$ systems in the compact pentaquark picture are constructed systematically for studying hidden charm pentaquark states.
