Abstract

We present progress in the evaluation of $$\gamma ^*N\rightarrow N^*(1535)$$ γ ∗ N → N ∗ ( 1535 ) transition form factors in a quark–diquark picture of these baryons. Our analysis is based upon the fully-consistent treatment of a vector $$\times $$ × vector contact interaction, embedded in the interlaced formalism of Schwinger–Dyson and Bethe–Salpeter equations.
