Entanglement suppression and emergent symmetries in hadron scatterings
Tao-Ran Hu, Su Chen, Katsuyoshi Sone +3
Recently entanglement suppression was proposed to be one potential origin of emergent symmetries. In this work, we extend this theoretical framework to accommodate particles with a…
Effect of eigenstates on spectra in coupled-channel scattering with the chiral unitary model
Takuma Nishibuchi, Tetsuo Hyodo
In recent years, as experimental data on the excited and states have accumulated, theoretical analyses based on chiral dynamics have also been actively pursued.…
Threshold cusp structures in multi-channel scattering
Katsuyoshi Sone, Tetsuo Hyodo
We study the behavior of the cusp structures focusing on the isospin symmetry breaking effects. The properties of the exotic hadrons are reflected in the shape of the cusp structur…
Eigenstates in coupled-channel scattering amplitude and their effects on spectrum
Takuma Nishibuchi, Tetsuo Hyodo
In general, discrete eigenstates such as resonances are represented by poles of the scattering amplitude, analytically continued to the complex energy plane. In multi-channel scatt…
Compositness and wave function of shallow bound states in relation to scattering observables
Ibuki Terashima, Tetsuo Hyodo
We study the internal structure of exotic hadrons, especially focusing on the relation between the compositeness and physical observables. Defined as the probability of finding had…
Properties of from hadronic potentials coupled to quarks
Ibuki Terashima, Tetsuo Hyodo
The concept of compositeness is used to quantitatively discuss the hadronic molecular nature in exotic hadrons. In this work, we develop a formulation to explicitly introduce the c…
Internal structure of and by using compositeness
Tomona Kinugawa, Tetsuo Hyodo
The internal structure of the near-threshold exotic hadrons, and , are studied by respecting the decay and coupled-channel contributions. The effective field theo…
General behavior of near-threshold hadron scattering for exotic hadrons
Katsuyoshi Sone, Tetsuo Hyodo
We discuss the general behavior of the near-threshold scattering amplitude with channel couplings. The signal of the exotic hadrons near the threshold may manifest as a dip structu…
