Abstract

We give an overview of our recent efforts to extract electromagnetic transition form factors for \(N^*\) and \({\varDelta }^*\) baryon resonances through a global analysis of the single-pion electroproductions off the proton within the ANL-Osaka dynamical coupled-channels approach. Preliminary results for the extracted form factors associated with \({\varDelta }(1232)3/2^+\) and the Roper resonance are presented, with emphasis on the complex-valued nature of the transition form factors defined by poles.
