论文摘要
在相对论的手性有效理论框架内计算完整的风味SU（3）八位字和解剖重子的自我富集。领先的非分析性手性行为是针对八位位和解剖质量得出的，并且适用于Lorentz一致的有限范围正规化，并应用了量规不变性，以说明Baryons的有限尺寸。使用四维偶极子形式，对各种介子 - 巴里昂环路对自能力的相对重要性进行了数值研究，这是偶极范围参数和梅森质量的函数，并且在相对论结果与重型龙子限制内的较早近似值之间进行了比较。
The self-energies of the full set of flavor SU(3) octet and decuplet baryons are computed within a relativistic chiral effective theory framework. The leading nonanalytic chiral behavior is derived for the octet and decuplet masses, and a finite-range regularization consistent with Lorentz and gauge invariance is applied to account for the finite size of the baryons. Using a four-dimensional dipole form factor, the relative importance of various meson-baryon loop contributions to the self-energies is studied numerically as a function of the dipole range parameter and meson mass, and comparison is made between the relativistic results and earlier approximations within the heavy baryon limit.
