Abstract: The K¯-induced production of Λ(1405) is investigated in K¯d → πΣn reactions based on coupled-channels chiral dynamics, in order to discuss the resonance position of the Λ(1405) in the K¯N channel. We find that the K¯d → Λ(1405)n process favors the production of Λ(1405) initiated by the K¯N channel. The present approach indicates that the Λ(1405)-resonance position is 1420MeV rather than 1405MeV in the πΣ invariant-mass spectra of K ¯d → πΣn reactions. This is consistent with an observed spectrum of the K¯d → π+Σ¯n with 686–844MeV/c incident K¯ by bubble chamber experiments done in the 70s. Our model also reproduces the measured Λ(1405) production cross-section.
