Abstract

• We calculated various range parameters and different strength parameters of Λ (1405) with resonance state for +-+-Σ π→ Σ π. Firstly we solved Schrodinger equation by using separable potential for +-+-Σ π→ Σ π channel to obtain various differential cross sections with energies for various strength parameters and different range parameters. It is reduced the resonance state of +- Σ π. Secondly, we investigated the various strength and range parameters of seperable potential for Λ (1405) resonance within KN frame work of KN +-→ Σ π coupled channel. It is observed that the parameter sets of KN interaction can be constructed for +- Σ π resonance and K-p bound state. Therefore, we constructed the new model A and B for KN interaction.
