The pi N -> pi pi N reaction around the N(1440) energy
Hiroyuki Kamano, Masaki Arima
We study the pi N -> pi pi N reaction around the N(1440) mass-shell energy. Considering the total cross sections and invariant mass distributions, we discuss the role of N(1440) an…
Chiral Symmetry and N*(1440) -> N pi pi Decay
H. Kamano, M. Morishita, M. Arima
The N*(1440) -> N pi pi decay is studied by making use of the chiral reduction formula. This formula suggests a scalar-isoscalar pion-baryon contact interaction which is absent in…
Excitation Spectrum in the Friedberg-Lee Model
H. Kowata, M. Arima
The excitation spectrum of the nucleon with the spin 1/2 is examined by using the Friedberg-Lee model containing the constituent quark and the scalar meson. An appropriate way of q…
Dynamical Test of Constituent Quark Models with Reactions
T. Yoshimoto, T. Sato, M. Arima +1
A dynamical approach is developed to predict the scattering amplitudes starting with the constituent quark models. The first step is to apply a variational method to solve the…
Nucleon resonances in the constituent quark model with chiral symmetry
H. Kowata, M. Arima, K. Masutani
The mass spectra of nucleon resonances with spin 1/2, 3/2, and 5/2 are systematically studied in the constituent quark model with meson-quark coupling, which is inspired by the spo…
