Compositeness of near-threshold exotic hadrons in systems with Coulomb and short-range interactions
Tomona Kinugawa, Tetsuo Hyodo
We study the universal properties of near-threshold -wave eigenstates in systems with Coulomb plus short-range interactions by analyzing their compositeness. Using a nonrelativi…
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…
Compositeness of near-threshold states in charged hadronic systems
Tomon Kinugawa, Tetsuo Hyodo
We quantify the internal structure of near-threshold bound, virtual, and resonance states in systems where Coulomb and short-range interactions coexist by evaluating the compositen…
Compositeness of near-threshold eigenstates with Coulomb plus short-range interactions
Tomona Kinugawa, Tetsuo Hyodo
We investigate the internal structure of near-threshold -wave eigenstates in a two-body system with Coulomb plus short-range interactions. Using a nonrelativistic effective fiel…
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…
Structure of near-threshold states in systems with Coulomb and short-range interactions
Tomona Kinugawa, Tetsuo Hyodo
We study the nature of near-threshold eigenstates in systems with the attractive Coulomb plus short-range interactions. Using a model providing the Coulomb-modified effective range…
Regularized Lednicky-Lyuboshitz formula for higher partial waves in femtoscopy
Koichi Murase, Tetsuo Hyodo
Femtoscopy is one of the promising experimental approaches to put constraints on interactions between various species of hadrons from the momentum correlation functions measured in…
Higher partial waves in femtoscopy
Koichi Murase, Tetsuo Hyodo
Femtoscopy is recently gaining more attention as a new approach complementary to scattering experiments for constraining hadron-hadron interactions. We discuss the effect of higher…
