  We study nucleon-to-delta electromagnetic transition form factors and
relations between them within the framework of holographic dual model of QCD
proposed by Sakai and Sugimoto. In this setup, baryons appear as topological
solitons of the five dimensional holographic gauge theory that describes a
tower of mesons and their interactions. We find a relativistic extension of the
nucleon-delta-vector meson interaction vertices and use these to calculate
transition form factors from holographic QCD. We observe that at low momentum
transfer, magnetic dipole, electric and Coulomb quadrupole form factors and
their ratios follow the patterns expected in the large N_c limit. Our results
at this approximation are in reasonable agreement with experiment.
