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…
