Effect of channel in the reactions
M. Hirata, K. Ochi, T. Takaki
A model for the two-pion photoproduction on the nucleon proposedearlier is modified to simultaneously explain the total cross sections and the invariant mass spectra. Using this mo…
Cooperative damping mechanism of the resonance in the nuclear photoabsorption
M. Hirata, K. Ochi, T. Takaki
We propose a resonance damping mechanism to explain the disappearance of the peaks around the position of the resonances higher than the resonance in the nuclear photoabsorptio…
Photoabsorption on a Nucleon in the D_{13} Resonance Energy Region
Kazuyuki Ochi, Michihiro Hirata, Takashi Takaki
We present a simple model for the reaction which reproduces the cross sections of the and channels over the range of the…
Phenomenological interaction between current quarks
Michihiro Hirata, Naoto Tsutsui
We construct a phenomenological model which describes the dynamical chiral symmetry breaking (DCSB) of QCD vacuum and reproduces meson spectra. Quark condensates, the pion decay co…
