Query: Structure of Lambda(1405) and construction of KbarN local potential
  based on chiral SU(3) dynamics   We develop the single-channel local potential for the KbarN system, which is
applicable to quantitative studies of Kbar bound states in nuclei. Because the
high precision measurement of the kaonic hydrogen by SIDDHARTA reduces the
uncertainty of the KbarN amplitude below the KbarN threshold, the local
potential should be calibrated in a wide energy region. We establish a new
method to construct the local potential focusing on the behavior of the
scattering amplitude in the complex energy plane. Applying this method, we
construct the KbarN potential based on the chiral coupled-channel approach with
the SIDDHARTA constraint. The wave function from the new potential indicates
the KbarN molecular structure of Lambda(1405).
