Local Meson-Baryon Coupled-Channels Potential for the Λ(1405)

A local coupled-channels (K) over bar N-pi Sigma-pi Lambda potential is constructed, equivalently reproducing the scattering amplitude in chiral SU(3) dynamics. By analyzing the wave function of the Lambda(1405), we show the (K) over bar N dominance of the upper pole within the two-pole structure of the Lambda(1405). The resulting potential will be useful for investigating (K) over bar few-nucleon systems including their coupled channels.
