$π N$ and $π π N$ Couplings of the $Δ (1232)$ and its Chiral Partners

K. Nagata, A. Hosaka, V. Dmitrasinovic

We investigate the interactions and chiral properties of the four spin-$\thalf$-baryons : $N^{-} (D_{13})$ , $N^{+} (P_{13})$ , $Δ^{+} (P_{33})$ and $Δ^{-} (D_{33})$ together with the nucleon. W…

Structure of the Nucleon and Roper Resonance with Diquark Correlations

K. Nagata, A. Hosaka

We investigate the electric form factors of the nucleon and Roper resonance using a quark-diquark model. We find that the charge radii of the nucleon and Roper resonance are almost…
