Isospin-breaking effects on the threshold cusp structures in - scattering
Katsuyoshi Sone, Tetsuo Hyodo
We discuss the isospin-breaking effects on threshold cusp structures in multichannel scattering near two-body thresholds. In hadronic systems with isospin symmetry, two or more nea…
Threshold Cusp Structures in the Presence of Isospin Symmetry Breaking
Katsuyoshi Sone, Tetsuo Hyodo
We study the behavior of the cusp structures focusing on the isospin-breaking effects. The properties of the near-threshold exotic hadrons are encoded in the shapes of the cusp str…
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…
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…
Entanglement Suppression, Quantum Statistics and Symmetries in Spin-3/2 Baryon Scatterings
Tao-Ran Hu, Katsuyoshi Sone, Feng-Kun Guo +2
We explore the interplay among entanglement suppression, quantum statistics and enhanced symmetries in the non-relativistic -wave scattering involving the lowest-lying spin-3/2…
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…
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…
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…
