Effects of N channels on the Spin-Orbit Force in -hypernuclei
Sachiko Takeuchi
Effects of the N channels on the spin-orbit force in -hypernuclei are investigated. It is found that the cancellation between the symmetric and the antisymmetric N spin-or…

Symmetric and Antisymmetric Spin-Orbit Forces in YN Interaction by a Quark Model
Sachiko Takeuchi
The symmetric and antisymmetric spin-orbit forces (SLS and ALS) in the YN interaction are investigated for relative P-wave systems by a valence quark model with the instanton-induc…

Weak $\Lam N\to NN$ Transition in the Direct Quark Mechanism
Takashi Inoue, Sachiko Takeuchi, Makoto Oka
The weak $\Lam N\to NN$ transition is studied in the valence quark model approach. The momentum transfer for this transition is so large that the short-distance two baryon dynamics…
