Abstract

Magnetic dipole moment form factor, GM(2)(Q2)G_M^{(2)}(Q^2), describing the radial excitation of decuplet baryons to octet baryons electromagnetic transitions as well as the ratios, RSM=14m224m22Q2+(m22Q2m12)2GC(2)(Q2)GM(2)(Q2)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 REM=GE(2)(Q2)GM(2)(Q2)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.
