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…
