Light-cone sum rules for radial excitation of decuplet to octet baryons electromagnetic transition form factors

Abstract

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, $R_{SM}=-\frac{1}{4m_2^2}\sqrt{4m_2^2{Q}^2+(m_2^2-Q^2-m_1^2{)}^2}\frac{G_C^{(2)}(Q^2)}{G_M^{(2)}(Q^2)}$ 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.
