Application of coupled-channel Complex Scaling Method to Λ(1405)

We have applied the coupled-channel Complex Scaling Method (ccCSM) to the excited baryon Lambda(1405) which is the important building block of kaonic nuclei. Lambda(1405) is treated as a resonant state of the meson-baryon coupled system, (K) over barN and pi Sigma. In this article, it is reported that the ccCSM works well even with an energy-dependent (K) over barN potential such as a chiral SU(3)-based potential. We have tested two cases: the self-consistency condition is imposed on I) real energy and II) complex energy. Then, the self-consistent solutions are obtained in both cases in the framework of the ccCSM.
