Structures of the Λ(1405) in the Skyrme model

The Λ(1405) is well-known as a candidate of an exotic hadron resonance. Historically, the Λ(1405) was identified with a bound state of the anti-kaon (Kbar) and the nucleon (N). However, it is now considered to be a resonance state of the KbarN and πΣ channels. There are many experimental and theoretical studies for the Λ(1405). In this talk, we have investigated the structures of the Λ(1405) in the Skyrme model, where a baryon is described by a soliton with finite structures. To do that, we derive the coupling constant for the KbarN-πΣ vertex.
