Lambda(1405) as a Resonance in the Baryon-Meson Scattering Coupled to the q^3 State in a Quark Model
Sachiko Takeuchi, Kiyotaka Shimizu
In order to describe Lambda(1405) as a resonance in the baryon-meson scattering, we have investigated q^3-q qbar scattering system with the flavor-singlet q^3 (0s)^2(0p) state (the…

Pentaquark as a NK^* bound state with TJ^P=0{3/2}^-
Sachiko Takeuchi, Kiyotaka Shimizu
We have investigated negative-parity uudd\bar{s} pentaquarks by employing a quark model with the meson exchange and the effective gluon exchange as qq and q\bar{q} interactions. Th…
