Abstract

The properties of the Λ(1405) resonance have been investigated from radiative decay of K^- p→ Yγ and photoproduction γp→ K⁺Λ(1405) within the framework of the isobar model. For a consistent result with recently measured branching ratios, the axial vector meson K₁(1270) is taken into account. Strong and electromagnetic coupling constants of Λ(1405) are extracted from these branching ratios and are applied to the analysis of K⁺Λ(1405) photoproduction. The total and differential cross sections are predicted.
