Photon induced Lambda(1520) production and the role of the K^* exchange
Hiroshi Toki, Carmen Garcia-Recio, Juan Nieves
We study the photon induced Lambda(1520) production in the effective Lagrangian method near threshold, E_γ^{LAB}<2 GeV, and in the quark-gluon string model at higher energies 3 GeV…
Roles of the tensor and pairing correlations on the halo formation in 11Li
Takayuki Myo, Kiyoshi Kato, Hiroshi Toki +1
We study the roles of the tensor and pairing correlations on the halo formation in 11Li with an extended 9Li+n+n model. We first solve the ground state of 9Li in the shell model ba…
Reflection asymmetric relativistic mean field approach and its application to the octupole deformed nucleus Ra
L. S. Geng, J. Meng, H. Toki
A Reflection ASymmetric Relativistic Mean Field (RAS-RMF) approach is developed by expanding the equations of motion for both the nucleons and the mesons on the eigenfunctions of t…
Effect of negative energy components for two-nucleon systems in the relativistic framework with the separable ansatz
Y. Manabe, A. Hosaka, H. Toki
We investigate the electromagnetic properties of the deuteron such as the charge and magnetic form factors by solving the Bethe-Salpeter equation (BSE) with the separable ansatz. I…
Effect of the tensor force in the exchange channel on the spin-orbit splitting in 23F in the Hartree-Fock framework
Satoru Sugimoto, Hiroshi Toki, Kiyomi Ikeda
We study the spin-orbit splitting (-splitting) for the proton d-orbits in 23F in the Hartree-Fock framework with the tensor force in the exchange channel. 23F has one more prot…
Infrared behavior of the Faddeev-Popov operator in Coulomb gauge QCD
Y. Nakagawa, A. Nakamura, T. Saito +1
We calculate the eigenvalue distribution of the Faddeev-Popov operator in Coulomb gauge QCD using quenched SU(3) lattice simulation. In the confinement phase, the density of the lo…
