K. Nagata, A. Hosaka, V. Dmitrasinovic
We investigate the interactions and chiral properties of the four spin-$\thalf$-baryons : , , and 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…
Structure of the Roper Resonance with Diquark Correlations
Keitaro Nagata, Atsushi Hosaka
We study electromagnetic properties of the nucleon and Roper resonance in a chiral quark-diquark model including two kinds of diquarks needed to describe the nucleon: scalar and ax…
Chiral Properties of Baryon Interpolating Fields
Keitaro Nagata, Atsushi Hosaka, V. Dmitrašinovi\' c
We study the chiral transformation properties of all possible local (non-derivative) interpolating field operators for baryons consisting of three quarks with two flavors, assuming…
Path-integral approach in a chiral quark-diquark model to the nucleon structure and interactions
Keitaro Nagata, Atsushi Hosaka
We study the structure of the nuclear force by using a path-integral hadronization approach in a chiral quark-diquark model. After the construction of the chiral quark-diquark mode…
