A Study of Ni-Substitution Effects on Heavy-Fermion CeCu2Si2 - Similarities between Ni Substitution and High-Pressure Effects -
Yoichi Ikeda, Shingo Araki, Tatsuo C. Kobayashi +3
The effects of Ni substitution on Ce(Cu1-xNix)2Si2 have been studied by specific heat and electrical resistivity measurements. The specific heat measurement has revealed that the e…
Lattice QCD approach to Nuclear Physics
Sinya Aoki, Takumi Doi, Tetsuo Hatsuda +6
We review recent progress of the HAL QCD method which was recently proposed to investigate hadron interactions in lattice QCD. The strategy to extract the energy-independent non-lo…
Hadron-Hadron Interactions from Imaginary-time Nambu-Bethe-Salpeter Wave Function on the Lattice
The HAL QCD Collaboration, Noriyoshi Ishii, Sinya Aoki +7
Imaginary-time Nambu-Bethe-Salpeter (NBS) wave function is introduced to extend our previous approach for hadron-hadron interactions on the lattice. Scattering states of hadrons wi…
Chiral SU(3) theory of antikaon-nucleon interactions with improved threshold constraints
Yoichi Ikeda, Tetsuo Hyodo, Wolfram Weise
-nucleon interactions are investigated in the framework of coupled-channels dynamics based on the next-to-leading order chiral SU(3) meson-baryon effective Lagrangian. A r…
