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…

Suppression of Pi NN* Coupling and Chiral Symmetry
D. Jido, Y. Nemoto, M. Oka +1
Meson-baryon couplings between positive and negative parity nucleons are investigated using two point correlation functions in the soft meson and the chiral limit. We find that the…
