Coupled-channel analysis

Coupled-channel analysis is a technique used in physics to study how different particle interactions influence each other. When particles, like mesons or nucleons, interact, they can do so through multiple pathways or channels—each representing a different possible outcome. These channels are interconnected, so changes in one can affect others. By analyzing all channels simultaneously, scientists can better understand complex resonance behaviors, scattering processes, or particle decays. This comprehensive approach provides a more accurate depiction of particle interactions, helping physicists uncover fundamental properties of matter and the forces governing subatomic particles.
