Comment on "Efimov States and their Fano Resonances in a Neutron-Rich Nucleus"

Abstract

By introducing a mass asymmetry in a non-Borromean three-body system, without changing the energy relations, the virtual state pole cannot move from the negative real axis of the complex energy plane (with nonzero width) and become a resonance, because the analytical structure of the unitarity cuts remains the same.Comment: To be published in PR
