Compositeness of near-threshold exotic hadrons with decay and coupled-channel effects

Tomona Kinugawa, Tetsuo Hyodo

The near-threshold exotic hadrons such as and are naively considered as the hadronic molecular state from the viewpoint of the low-energy universality. However,…

Analysis of resonance and scattering length with chiral unitary approach

Takuma Nishibuchi, Tetsuo Hyodo

We study the resonance near the threshold in the light of the recent experimental constraints. The Belle collaboration have found a resonance peak of …

Hadron-hadron potentials coupled to quark degrees of freedom for exotic hadrons

Ibuki Terashima, Tetsuo Hyodo

We study the properties of the hadron-hadron potentials and quark-antiquark potentials from the viewpoint of the channel coupling. We demonstrate that, for finite quark masses, the…

Compositeness of and by considering decay and coupled-channels effects

Tomona Kinugawa, Tetsuo Hyodo

The compositeness of weakly bound states is discussed using the effective field theory from the viewpoint of the low-energy universality. We introduce a model with coupling of the…

Analysis of coupled-channel potentials with quark and hadron degrees of freedom

Ibuki Terashima, Tetsuo Hyodo

The quark-antiquark potentials are known to be confining in the absence of the pair creation. On the other hand, the inter-hadron potentials vanish at large distance, be…

Estimation of compositeness with correction terms

Tomona Kinugawa, Tetsuo Hyodo

The compositeness is defined as the probability to observe the composite structure such as the hadronic molecule component in a bound state. One of the model-independent approa…
