论文摘要
磁性偶极矩形式，$ g_m^{（2）}（q^2）$，描述了解剖重子对八位八元的bary子电磁过渡和比率的辐射激发，$ r_ {sm} = - \ frac {1}} q^2 -m_1^2）^2} \ frac {g_c^{（2）}（q^2）} {g_m^{（2）}（q^2）} $ and $ r_ {em r_ {em} = - \ \ frac {g_e^{（q^2）}（q^2）}在轻单元规则的框架中。我们还估计了U-Spin对称性的违规程度。多极形式因子获得的结果可用于搜索径向激发的巴里昂状态的性质。
Magnetic dipole moment form factor, $G_M^{(2)}(Q^2)$, describing the radial excitation of decuplet baryons to octet baryons electromagnetic transitions as well as the ratios, $R_{SM} = -\frac{1}{4 m_2^2} \sqrt{4 m_2^2 Q^2 + (m_2^2 - Q^2 -m_1^2)^2} \frac{G_C^{(2)}(Q^2)}{G_M^{(2)}(Q^2)}$ and $R_{EM} = -\frac{G_E^{(2)}(Q^2)}{G_M^{(2)}(Q^2)}$ are calculated in the framework of light-cone sum rules. We also estimate the degree of the violation of U-spin symmetry. The obtained results for the multipole form factors can be useful in searching the properties of radially excited baryon states.
