Abstract

The form factors of $γ^{*} N \to Δ (1600)$ transition is calculated within the light-cone sum rules assuming that $Δ^{+} (1600)$ is the first radial excitation of $Δ (1232)$ . The $Q^{2}$ dependence of the magnetic dipole $G ~_{M} (Q^{2})$ , electric quadrupole $G ~_{E} (Q^{2})$ , and Coulomb quadrupole $G ~_{c} (Q^{2})$ form factors are investigated. Moreover, the $Q^{2}$ dependence of the ratios $R_{E M} = - \frac{G ~ _{E} ( Q ^{2} )}{G ~ _{M} Q ^{2}}$ and $R_{S M} = - \frac{1}{4 m _{Δ (1600)}^{2}} 4 m_{Δ (1600)}^{2} Q^{2} + (m_{Δ (1600)}^{2} - Q^{2} - m_{N}^{2})^{2} \frac{G ~ _{c} ( Q ^{2} )}{G ~ _{M} ( Q ^{2} )}$ are studied. Finally, our predictions on $G ~_{M} (Q^{2})$ , $G ~_{E} (Q^{2})$ , and $G ~_{C} (Q^{2})$ are compared with the results of other theoretical approaches.
