论文摘要
由重味baryon块的精确测量的动机，我们通过在重子内采用筛选效果来分析夸克电荷的修饰。此外，我们计算出使用同胞对称性破坏的诱人的重子的同胞质量分裂。因此，我们获得了$ j^p = \ frac {1} {2} {2}^+$和$ \ frac {3} {2} {2}^+$ baryons的质量，磁性矩和过渡时刻和$ \ frac {3} {2}^+\ to \ frac {1} {2} {2}^{（\ prime）+} $ transilitions。最后，我们将状态混合的效果包括在口味退化的重生磁和过渡矩以及M1过渡衰减宽度中的影响。
Motivated by the precision measurements of heavy flavor baryon masses, we analyze the modification of quark charge by employing the screening effect inside the baryon. In addition, we calculate the isospin mass splitting up to charmed baryons employing isospin symmetry breaking. Consequently, we obtain the masses, magnetic moments, and transition moments of $J^P=\frac{1}{2}^+$ and $\frac{3}{2}^+$ baryons to predict radiative decay widths for $\frac{1}{2}^{\prime +} \to \frac{1}{2}^+$ and $\frac{3}{2}^+\to \frac{1}{2}^{(\prime)+}$ transitions. Finally, we include the effects of state mixing in flavor degenerate baryon magnetic and transition moments, as well as M1 transition decay widths.
