Radiative Decays of the in the Charmonium-Molecule Hybrid Picture
Sachiko Takeuchi, Makoto Takizawa, Kiyotaka Shimizu
The X(3872) radiative decay is discussed by employing a two-meson multichannel model with the charmonium components, which explains many of the other observed features of X(3872).…
On the origin of the narrow peak and the isospin symmetry breaking of the (3872)
Sachiko Takeuchi, Kiyotaka Shimizu, Makoto Takizawa
The (3872) formation and decay processes in the -decay are investigated by a -two-meson hybrid model. The two-meson state consists of the , $D^+D^…
Charmonium and meson-molecule hybrid tetraquarks - Vector meson width and the isospin breaking in the X(3872) decay
Sachiko Takeuchi, Kiyotaka Shimizu, Makoto Takizawa
In the X(3872) decay, both of the J/ψππ and J/ψπππ branching fractions are observed experimentally, and their sizes are comparable to each other. In order to clarify the mechanism…
Lambda(1405) in a baryon-meson scattering with a bound state embedded in the continuum
Sachiko Takeuchi, Kiyotaka Shimizu
We investigate Lambda(1405) as a resonance in a coupled channel baryon-meson scattering with a `bound state embedded in the continuum'(BSEC). This BSEC is introduced by hand, as a…
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…
