摘要：

鉴于手征组分夸克模型（$χ$ CQM）在研究基态重子的低能强子矩阵元方面的进展，我们将该模型推广到研究基态重子的跃迁性质。用显式价夸克自旋、海夸克自旋和海夸克轨道角动量贡献计算了从$J^P=\frac{3}{2}^+$十重态到$J^P=\frac{1}{2}^+$八重态重子跃迁的磁矩。由于实验数据是可用的，只有几个过渡，我们比较了我们的结果与其他可用的模型的结果。本文还讨论了夸克禁闭引起的手征对称性破缺和SU（3）对称性破缺等复杂效应的意义。

英文摘要：

In light of the developments of the chiral constituent quark model ($χ$CQM) in studying low energy hadronic matrix elements of the ground-state baryons, we have extended this model to investigate their transition properties. The magnetic moments of transitions from the $J^P=\frac{3}{2}^+$ decuplet to $J^P=\frac{1}{2}^+$ octet baryons have been calculated with explicit valence quark spin, sea quark spin and sea quark orbital angular momentum contributions. Since the experimental data is available for only a few transitions, we have compared our results with the results of other available models. The implications of other complicated effects such as chiral symmetry breaking and SU(3) symmetry breaking arising due to confinement of quarks have also been discussed.
