Structure of Bound States with Coulomb plus Short-range Interaction
Chisato Uno, Tetsuo Hyodo
We study the structure of bound states appearing in systems governed by the Coulomb and short-range interactions. We analyze the binding energies and wave functions of the bound st…
Internal structure of near-threshold states using compositeness
Tomona Kinugawa, Tetsuo Hyodo
Understanding the internal structure of near-threshold states is essential for revealing the nature of exotic hadrons. Motivated by this challenge, we discuss the clustering struct…
Compositeness of near-threshold states with repulsive Coulomb interaction combined with short-range potential
Tomona Kinugawa, Tetsuo Hyodo
We investigate the internal structure of near-threshold states in a system with a repulsive Coulomb interaction combined with a short-range potential, using the compositeness. We c…
Femtoscopy for exotic hadrons and nuclei
Tetsuo Hyodo
In high energy collision experiments with multiple hadron productions, the momentum distribution of the measured hadron pair shows a correlation due to the final state hadron inter…
Study of hadron interactions and compositeness
Tetsuo Hyodo
Plenty of hadrons have been established experimentally, yet the nonperturbative nature of the strong interaction complicates a comprehensive understanding of their internal structu…
Compositeness of hadrons, nuclei, and atomic systems
Tomona Kinugawa, Tetsuo Hyodo
Recent observations of exotic hadrons have stimulated the theoretical investigation of the internal structure of hadrons. While all hadrons are ultimately composed of quarks and gl…
