论文摘要
可以通过假设全局$ su(3)$颜色对称性来很好地解释颜色限制。强子被视为有限尺寸的袋子,其能量是由强子内的颜色场贡献的。在较大的动量框架中,可以对强子的质量进行量化,并且可以表示为涉及的夸克当前质量的总和,以及依赖通用参数的风味独立术语,可以识别为QCD痕量痕迹异常的贡献。该术语描述了雷格(Regge)的浅色强子质量的轨迹,可以从中确定参数,并使最小的载体中质量质量和baryon质量分别为761 MeV和935 MeV。质量公式可以解释强子光谱的许多特征。
The color confinement can be decently explained by assuming the global $SU(3)$ color symmetry. A hadron is viewed as a bag of a finite size, whose energy is contributed by the color fields within the hadron. In the large momentum frame, the mass of a hadron can be quantized and can be expressed as the sum of the current masses of quarks involved plus a flavor independent term which depends on a universal parameter and can be identified to be the contribution from the QCD trace anomaly. This term depicts the Regge's trajectories of light hadron masses, from which the parameter can be determined and gives the minimal vector meson mass and baryon mass to be 761 MeV and 935 MeV, respectively. The mass formula can explain many features of the hadron spectroscopy.
