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,…

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…
