Yet, its properties have not been consistently explained by effective models of QCD, such as the non-relativistic quark model. In this paper, we propose an alternative approach in the Sakai-Sugimoto model that is one of the holographic models of QCD. In particular, we analyze the helicity amplitude of the electromagnetic transitions at the leading of 't Hooft coupling 
. The model incorporates baryon structure at short distance by nonlinear mesons surrounded by meson clouds at long distance. We demonstrate that the recently observed data by CLAS are explained in the present approach.

, is studied in a constituent quark model. Four-body problem is solved in a variational method where the real scaling technique is used to identify resonant states above the fall-apart decay thresholds. In addition to the two bound states that were reported in the previous study we have found several narrow resonant states above the 
and 
thresholds. Their structures are studied and are interpreted by the quark dynamics. A narrow resonance with spin-parity 
is found to be a mixed state of a compact tetraquark and a scattering state. This is driven by a strong color Coulombic attraction between the 
quarks. Negative-parity excited resonances with 
, 
and 
form a triplet under the heavy-quark spin symmetry. It turns out that they share a similar structure to the 
-mode of a singly heavy baryon as a result of the strongly attractive correlation for the doubly heavy diquark.
