Abstract

The properties of the $\Lambda(1405)$ resonance have been investigated from radiative decay of $K^- p\to Y\gamma$ and photoproduction $\gamma p\to K^+\Lambda(1405)$ within the framework of the isobar model. For a consistent result with recently measured branching ratios, the axial vector meson $K_1(1270)$ is taken into account. Strong and electromagnetic coupling constants of $\Lambda(1405)$ are extracted from these branching ratios and are applied to the analysis of $K^+\Lambda(1405)$ photoproduction. The total and differential cross sections are predicted.
