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…
