Quark-Pauli effects in three octet-baryons
C. Nakamoto, Y. Suzuki
To sustain a neutron star with about two times the solar mass, multi baryons including hyperons are expected to produce repulsive effects in the interior of its high baryon-density…
Baryon-baryon interactions in the SU6 quark model and their applications to light nuclear systems
Y. Fujiwara, Y. Suzuki, C. Nakamoto
Interactions between the octet-baryons (B8) in the spin-flavor SU6 quark model are investigated in a unified coupled-channels framework of the resonating-group method (RGM). The in…
Quark-Model Baryon-Baryon Interaction and its Applications to Hypernuclei
Y. Fujiwara, C. Nakamoto, Y. Suzuki +2
The quark-model baryon-baryon interaction fss2, proposed by the Kyoto-Niigata group, is a unified model for the complete baryon octet (B_8=N, Lambda, Sigma and Xi), which is formul…
Interactions between Octet Baryons in the SU_6 Quark model
Y. Fujiwara, M. Kohno, C. Nakamoto +1
The baryon-baryon interactions for the complete baryon octet (B_8) are investigated in a unified framework of the resonating-group method, in which the spin-flavor SU_6 quark-model…
A Realistic Description of Nucleon-Nucleon and Hyperon-Nucleon Interactions in the SU_6 Quark Model
Y. Fujiwara, T. Fujita, M. Kohno +2
We upgrade a SU_6 quark-model description for the nucleon-nucleon and hyperon-nucleon interactions by improving the effective meson-exchange potentials acting between quarks. For t…
G-Matrix Equation in the Resonating-Group Method
Yoshikazu Fujiwara, Michio Kohno, Choki Nakamoto +1
The G-matrix equation is most straightforwardly formulated in the resonating-group method if the quark-exchange kernel is directly used as the driving term for the infinite sum of…
Study of Light Lambda- and Lambda Lambda-Hypernuclei with the Stochastic Variational Method and Effective Lambda N Potentials
Hidekatsu Nemura, Yasuyuki Suzuki, Yoshikazu Fujiwara +1
We first determine the Lambda-N S-wave phase shifts so as to reproduce the experimental Lambda separation energies of A=3, 4 Lambda-hypernuclei, and then construct three phase-equi…
Lippmann-Schwinger Resonating-Group Formalism for NN and YN Interactions in an SU6 Quark Model
Yoshikazu Fujiwara, Michio Kohno, Tadashi Fujita +2
We formulate a Lippmann-Schwinger-type resonating-group equation to calculate invariant amplitudes of the quark-model baryon-baryon interaction. When applied to our recent SU6 quar…
Hyperon Single-Particle Potentials Calculated from SU6 Quark-Model Baryon-Baryon Interactions
M. Kohno, Y. Fujiwara, T. Fujita +2
Using the SU6 quark-model baryon-baryon interaction recently developed by the Kyoto-Niigata group, we calculate NN, Lambda N and Sigma N G-matrices in ordinary nuclear matter. This…
Single-Particle Spin-Orbit Strengths of the Nucleon and Hyperons by SU6 Quark-Model
Y. Fujiwara, M. Kohno, T. Fujita +2
The quark-model hyperon-nucleon interaction suggests an important antisymmetric spin-orbit component. It is generated from a color analogue of the Fermi-Breit interaction dominatin…
