Entanglement suppression for scattering
Katsuyoshi Sone, Tao-Ran Hu, Feng-Kun Guo +2
We study entanglement suppression in -wave scattering, where each baryon has spin . By treating the -matrix as a quantum operator acting on the spin states, we quan…
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…

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…
Structure of near-threshold resonances with new interpretation scheme of complex compositeness
Tomona Kinugawa, Tetsuo Hyodo
The nature of near-threshold resonances is quantitatively studied with a new interpretation scheme using the complex compositeness. A difficulty was known in the understanding of t…
General amplitude of near-threshold hadron scattering for exotic hadrons
Katsuyoshi Sone, Tetsuo Hyodo
We discuss the general behavior of the scattering amplitude with channel couplings near the two-body threshold. It is known that the Flatté amplitude, which is often used in the an…
Compositeness of near-threshold -wave resonances
Tomona Kinugawa, Tetsuo Hyodo
The near-threshold clustering phenomenon is well understood by the low-energy universality, for shallow bound states below the threshold. Nevertheless, the characteristics of reson…

Ibuki Terashima, Tetsuo Hyodo
To study the internal structure of the exotic hadron , considering the coupled-channel potential between quarks and hadrons is necessary because is regarded as a…
Analysis of resonance with chiral unitary approach
Takuma Nishibuchi, Tetsuo Hyodo
Recently, the resonance has attracted much attention, thanks to detailed experimental data by the Belle and ALICE collaborations. This experimental progress has prepared…
Near-threshold hadron scattering with effective field theory
Katsuyoshi Sone, Tetsuo Hyodo
When an exotic hadron locates near the threshold with the channel couplings, the internal structure of the exotic hadron is related to the scattering length. To incorporate the thr…
