Photoproduction of Λ(1405) and Σ0(1385) on the Proton at $${{\rm E}_{\gamma}}$$ = 1.5–3.0 GeV at SPring-8/LEPS

Abstract

The missing mass spectra of \({\gamma p \rightarrow K^{+}X}\) for \({\gamma p \rightarrow K^{+} n \pi^{+}\pi^{-}}\) reaction were measured to obtain the spectrum of Λ(1405). The spectra were measured for two charged decay modes of Λ(1405) separately and they were combined to cancel the effect of interference between the isospin 0 and 1 terms of the Σπ scattering amplitudes. Our goal is to obtain the differential cross section of Λ(1405) and Σ0(1385) photoproduction. The preliminary results are presented here.
