    "abstract": "The Lambda(1405) resonance is studied by a chiral unitary approach, in which\nthe resonance is dynamically generated in coupled-channel meson-baryon\nscattering. Investigating the analytic structure of the scattering amplitudes\nobtained by the chiral unitary approach, we find two poles around the energies\nof the Lambda(1405) coupling differently to the meson-baryon states. We reach\nthe conclusion that the Lambda(1405) resonance seen in experiments is not just\none single resonance, but a superposition of these two states.",
